In January 1989, tens of thousands of electronics dealers, manufacturers, journalists, buyers, and sales representatives poured into Las Vegas for the International Winter Consumer Electronics Show. Televisions, compact disc players, home-office equipment, telephones, audio systems, and countless electronic gadgets filled the convention halls, but one corner of the business was becoming impossible to overlook.
Video games were booming again.
Only a few years earlier, the American home video game business had been written off after the spectacular collapse of the early 1980s. By the opening of the 1989 Winter CES, Nintendo had transformed that story. The Nintendo Entertainment System had become one of the most desirable products in American homes; major publishers were scrambling for space on the platform; Sega was trying to strengthen the Master System; Atari Games and its Tengen subsidiary were challenging Nintendo’s control of NES cartridges, and hardware designers were promising that players would soon control games with punches, hand gestures, and movements instead of an ordinary directional pad.
Some of those ideas became landmarks. Others became cautionary tales. A few products shown or promoted in Las Vegas never reached stores in the form envisioned there.
Together, they made the January 1989 Winter CES one of the most revealing trade shows of the Nintendo Entertainment System era.
Las Vegas at the Height of the Video Game Comeback
The 1989 International Winter Consumer Electronics Show officially ran from Saturday, January 7, through Tuesday, January 10. Advance registration materials from the Electronic Industries Association described it as a trade-only event. Attendees had to be at least eighteen years old, ordinary over-the-counter sales were prohibited, and the gathering was intended for retailers, distributors, manufacturers, buyers, representatives, marketers, analysts, and other members of the electronics business.
The scale was enormous. A post-show report in Cash Box said a record 1,430 exhibitors occupied 774,682 square feet of exhibition space. More than 56,000 attendees had been verified by the end of the first day, and the final attendance figure was reported as 70,138. Show officials called it the largest and most successful Winter CES to that point.
Video games were still only one category inside a much larger consumer-electronics industry, but contemporary reporting made clear how dramatically their position had changed. Billboard described games as the fastest-growing consumer-electronics category and one of the dominant attractions of the Las Vegas show. The magazine cited an industry figure of more than $2.3 billion for video games in 1988, with expectations that the business could climb considerably higher in 1989.
That enthusiasm carried a special historical weight. The American console business had risen rapidly in the early 1980s, crashed almost as quickly, and then returned under very different conditions. Nintendo had convinced retailers that a home video game system could again be a dependable mass-market product, but the company had done so while keeping unusually tight control over who could manufacture software for its machine.
By January 1989, that system was producing both extraordinary commercial success and increasingly serious conflict.
Nintendo Becomes the Center of the Show
Anyone trying to understand the video game portion of Winter CES 1989 has to begin with Nintendo.
Dave DiMartino’s contemporary report for Billboard described Nintendo’s exhibit as a vast and crowded attraction where attendees gathered around color monitors to play NES games while Nintendo merchandise, including shirts, towels, bags, and copies of Nintendo Power, surrounded them. His headline made the point directly: video games had stolen the show.
Computer Entertainer, one of the most valuable surviving sources for the event, remembered Nintendo’s exhibit in equally theatrical language. Its January issue compared the huge booth to a three-ring circus filled with attractions and surrounded by more than thirty Nintendo licensees. The publication’s broader CES report called the atmosphere among game and computer entertainment companies busy, exciting, and generally upbeat.
Nintendo’s strength did not rest on one game. The important sight was the ecosystem forming around the NES.
Publishers and licensees were preparing titles that would help define the next stage of the system’s American life. Contemporary coverage pointed to games including Mega Man 2, Teenage Mutant Ninja Turtles, Ninja Gaiden, The Guardian Legend, Who Framed Roger Rabbit?, Ironsword, Hoops, Goal!, Pinbot, Marble Madness, Operation Wolf, Shadowgate, and many others. Nintendo’s own March and April 1989 issue of Nintendo Power devoted several pages to the CES trip and identified the show as an important preview of products heading toward NES owners.
The variety was striking. Taito brought arcade conversions. Capcom had its growing NES lineup. Konami and its Ultra label were becoming major forces. Milton Bradley was moving familiar properties and arcade-derived games toward the console market. Kemco-Seika was preparing Shadowgate. Sunsoft announced games including Fester’s Quest. Seta was entering the American market with The Adventures of Tom Sawyer.
The NES was no longer simply Nintendo’s machine. It had become the center of an industry built around dozens of outside companies that wanted access to Nintendo’s customers.
That success was exactly what made the conflict happening nearby so important.
Tengen Challenges Nintendo
Only weeks before CES, Atari Games and its Tengen subsidiary had launched a direct challenge to the way Nintendo controlled NES software.
Tengen had previously worked as an authorized Nintendo licensee, but by December 1988 the company announced that it would begin manufacturing its own Nintendo-compatible cartridges rather than relying on Nintendo to produce them. Tengen argued that Nintendo’s control over cartridge manufacturing had contributed to supply shortages and gave Nintendo too much authority over the software market.
On December 12, United Press International reported that Tengen had already begun selling independently manufactured versions of Pac-Man, Gauntlet, and R.B.I. Baseball. The company also announced that four additional NES-compatible games would be introduced at Winter CES on January 7: Super Sprint, Rolling Thunder, Vindicators, and Tetris.
Atari Games simultaneously accused Nintendo of monopolistic practices. Nintendo responded aggressively. On January 5, only two days before CES opened, Nintendo announced a countersuit alleging breach of contract, trademark violations, unfair competition, and other wrongdoing connected with Atari Games and Tengen. The legal fight was therefore not distant background news. It was unfolding as company representatives arrived in Las Vegas.
Tengen still appeared with its products.
Contemporary records show Super Sprint, Rolling Thunder, Vindicators, and Tetris among the NES titles being presented, while the company also pushed Atari Games properties toward home computers. The confrontation represented something much larger than a disagreement between two publishers. It asked who would control the emerging console software economy.
Nintendo’s position was that its security and licensing system protected the quality and reliability of software sold for the NES. Tengen’s position was that Nintendo’s restrictions allowed one company to dictate supply and access to a rapidly growing market.
That disagreement would continue through years of litigation.
The Tetris shown in connection with Tengen added another layer of historical importance. The famous puzzle game would become the center of a separate rights battle later in 1989, ultimately forcing Tengen’s NES version from the market. At Winter CES, however, that outcome was still in the future. Visitors were seeing a company confidently presenting a game that would soon become one of the most famous contested releases in video game history.
U-Force Steals the Spotlight
For all the major publishers and coming games, one of the most talked-about attractions at the show was not a game at all.
It was a controller that players did not have to touch.
Broderbund’s U-Force opened like a small laptop and created a sensing area in front of the player. Instead of gripping a directional pad, the user moved hands and arms through an invisible detection field. Those movements were translated into normal NES controller commands.
The idea sounded like science fiction in 1989.
Computer Entertainer put U-Force on the front page of its January issue under the headline “Broderbund Steals the Show with U-FORCE.” The publication said Broderbund held demonstrations roughly every fifteen or twenty minutes during the four-day convention and consistently attracted large crowds. One demonstration used Mike Tyson’s Punch-Out!!, allowing a player to throw punches into the air and watch the boxer on the television respond.
Gregg Keizer of COMPUTE! also saw the device demonstrated at Winter CES. He described the controller as detecting motion and velocity inside an invisible area roughly a foot across. A player could punch while playing Mike Tyson’s Punch-Out!! or imitate the controls of an aircraft in Top Gun. Broderbund expected a price of $69.95, roughly the cost of two NES cartridges at the time.
The concept was remarkable because it tried to change what a video game controller was.
Since the earliest home consoles, the player had generally held something in the hands and pressed buttons, moved a joystick, turned a dial, or manipulated a directional control. U-Force proposed that empty space itself could become the controller.
Modern motion gaming makes that concept sound familiar. In 1989, it was not.
Broderbund was betting that body movement could become part of the game experience almost two decades before Nintendo’s Wii made motion control a mainstream phenomenon. The technology was much more limited than later systems, and the commercial U-Force never lived up to the excitement of its CES demonstrations, but the reaction in Las Vegas reveals how hungry the industry was for a new way to play.
The Power Glove Reaches for the Future
U-Force was not alone.
Mattel also brought a prototype of the Power Glove, an accessory worn on the player’s hand and forearm that translated gestures and movement into NES commands.
The March 1989 issue of Computer Entertainer specifically stated that the Power Glove had first been shown in prototype form at the January Winter CES before appearing again at Toy Fair in February. Its reporters watched demonstrations using both Mike Tyson’s Punch-Out!! and Rad Racer. A clenched fist and punching motion could trigger a punch on the screen, while hand movement could be converted into steering commands for the racing game.
Nintendo also gave the Power Glove significant attention in its CES coverage. The device fit perfectly with the futuristic image companies were trying to create around new kinds of game control. Instead of sitting quietly in front of a television pressing buttons, the player appeared to become physically connected to the software.
Both U-Force and the Power Glove would eventually earn reputations far less flattering than the excitement surrounding their CES appearances. Neither replaced the ordinary gamepad. Neither became the beginning of a new controller standard.
Yet judging them only by their later shortcomings misses what their presence at CES represented.
Video game companies were already asking questions that would return repeatedly over the following decades. Could cameras, sensors, gloves, infrared beams, or body movement replace buttons? Could a game understand where the player’s hands were located in physical space? Could the television become something more interactive than a screen connected to a controller?
The 1989 answers were primitive, but the questions were remarkably modern.
A Strange Glimpse of the Games That Never Were
Trade shows also preserve versions of the future that never happened.
One of the most fascinating surviving artifacts from Winter CES 1989 comes from LJN Toys. The Video Game History Foundation preserves an “Enteractive Video Games” sales and publicity kit dated January 7 through January 10, 1989. Among its contents is promotional material for an A Nightmare on Elm Street NES game that appears to be completely different from the title LJN eventually released.
In the surviving flyer, the player apparently took the role of Freddy Krueger himself.
The Video Game History Foundation identifies the proposed game as an unproduced adaptation and notes that it appears unrelated to the later commercial NES release.
That single piece of paper demonstrates why CES material can be so valuable to video game historians.
A released cartridge tells us what ultimately survived development, licensing, marketing decisions, deadlines, and budgets. A trade-show folder can reveal what a publisher hoped to sell before those decisions were final. In some cases, CES material becomes the only surviving evidence that a completely different version of a game was ever planned.
Winter CES was filled with products in that uncertain state. Some were finished. Some were prototypes. Some would change names. Some would be delayed. Some would disappear.
The show floor was not a catalog of the future. It was a collection of possible futures competing to become real.
Sega Fights for Space Beside Nintendo
Nintendo dominated the American console market, but Sega was not absent from the show.
One of the easiest mistakes in retelling Winter CES 1989 is to project the coming 16-bit console war backward onto January. Sega’s American Genesis launch was still months away. Contemporary January reporting focuses primarily on the Sega Master System and its 1989 software rather than on a grand Genesis confrontation with Nintendo.
Computer Entertainer described plenty of activity at Sega’s booth and highlighted Altered Beast as one of the company’s major coming games. The Master System lineup also included or promoted games such as Vigilante, Rastan, Reggie Jackson Baseball, Poseidon Wars 3-D, Ys: The Vanished Omens, Time Soldiers, Out Run 3-D, and other arcade and computer-inspired releases.
There was also evidence that Sega was trying to broaden outside support. Companies such as Activision, Parker Brothers, and Absolute Entertainment were associated with Master System projects.
That was important because Nintendo’s greatest strength was no longer simply its own software. It was the dense network of outside publishers feeding games into the NES library.
Sega needed more of the same.
The Master System never approached Nintendo’s American dominance, but the strategy visible in early 1989 pointed toward what Sega would soon attempt with the Genesis: better arcade conversions, aggressive promotion, sports games, recognizable licenses, and a stronger effort to make Sega’s hardware look like a serious alternative to Nintendo.
The great Genesis versus Super Nintendo rivalry still lay ahead. Winter CES 1989 belonged to the period immediately before it.
Computer Games Refuse to Disappear
The explosion of the NES can make late-1980s game history look more console-centered than it really was.
Winter CES also remained an important place for computer entertainment.
Bill Kunkel and Joyce Worley reported in ST-Log that approximately three dozen Atari ST entertainment titles were previewed or announced at the 1989 Winter CES. They discussed the growing flow of European games into the American market and highlighted the way Atari ST software increasingly benefited from conversions of Amiga titles.
Computer Entertainer likewise moved between console and computer software throughout its CES coverage. Its reporters encountered games for MS-DOS, Commodore 64 and 128, Amiga, Atari ST, Macintosh, Apple IIGS, and other machines. Titles connected to companies such as Electronic Arts, Sierra, Cinemaware, Epyx, Taito, Data East, Spectrum HoloByte, Strategic Simulations, and The Software Toolworks shared the larger entertainment landscape with Nintendo and Sega.
This mattered because the boundaries between the computer and console industries were becoming increasingly porous.
Companies ported arcade games to computers, computer adventures to consoles, console properties back to computers, and successful ideas across nearly every available platform. Publishers that had once thought of themselves primarily as computer software houses were looking at the size of the NES audience and reconsidering their place in the market.
Broderbund’s U-Force was one of the clearest examples. A company famous for computer software had suddenly become the creator of one of the most talked-about NES hardware accessories at CES.
The center of gravity was shifting.
The Epyx Handy Waits in the Wings
Away from the loudest Nintendo demonstrations, another prototype hinted at a different future for video games.
Epyx had been developing a portable color game system known as the Handy. Created with major contributions from former Amiga engineers R. J. Mical and Dave Needle and associated with former Amiga executive David Morse, the device was technologically ambitious for a handheld machine of the late 1980s.
Epyx showed the Handy to industry insiders at Winter CES in January 1989 while searching for a company capable of helping bring the system to market. Later histories of the machine identify January 7, 1989 as its first CES presentation.
The company ultimately found its partner in Atari.
By the Summer CES in June, the machine would reappear under Atari’s banner as the Portable Color Entertainment System, soon renamed the Atari Lynx.
That distinction matters.
The Atari-branded Lynx belongs primarily to the story of the June 1989 Summer CES. The January show belongs to the earlier and more fragile moment when the machine was still the Epyx Handy, an impressive prototype whose creators needed financial and manufacturing support.
In hindsight, it is one of the most consequential quiet demonstrations associated with the January gathering. While most attention centered on the NES, Epyx was showing part of the coming handheld war.
Nintendo’s Game Boy would soon dominate that market, but the Lynx would demonstrate features that seemed almost impossibly advanced beside Nintendo’s monochrome portable, including a backlit color display and sophisticated graphics hardware.
At Winter CES, however, none of that history had been settled.
It was still simply a promising machine looking for a future.
What Winter CES 1989 Really Showed
The temptation when looking backward at a trade show is to search only for famous debuts.
Winter CES 1989 is more valuable when viewed as a snapshot of the whole industry.
Nintendo stood at the center of an extraordinary commercial revival. Its booth, its licensees, and the sheer quantity of NES software demonstrated that the American console market had not merely recovered from the crash. It had reorganized itself around Nintendo.
Tengen showed the limits of that arrangement by challenging Nintendo’s authority over cartridge production and software licensing.
U-Force and the Power Glove showed designers trying to break free from the conventional controller.
Sega showed a company still fighting with the Master System while preparing for a much larger challenge later in the year.
Computer publishers demonstrated that the home computer game market remained creative and substantial even as consoles captured more attention.
LJN’s surviving promotional materials preserved games and concepts that might otherwise have vanished from history.
Epyx quietly carried a color handheld prototype into Las Vegas and searched for someone willing to help manufacture it.
These stories were not separate. They were all symptoms of the same thing.
Video games had become important enough again that companies were willing to fight over them, sue over them, invent strange new hardware for them, spend heavily to promote them, and take major technological risks trying to predict where players would go next.
Before the 16-Bit War
The timing of the January show makes it especially important.
Later in 1989, Sega would launch the Genesis in the United States. NEC would bring the TurboGrafx-16 to the American market. Nintendo would release the Game Boy. Atari would transform Epyx’s Handy into the Lynx. The Tetris rights battle would explode. The Power Glove and U-Force would reach consumers and discover that a spectacular trade-show demonstration did not necessarily translate into a great everyday controller.
By the end of the year, many of the uncertainties visible in Las Vegas would have begun turning into products, lawsuits, victories, disappointments, and rivalries.
But on January 7, 1989, those outcomes were still open.
That is what makes the Winter Consumer Electronics Show such a valuable moment in video game history. It sits between eras.
The NES revival of the mid-1980s had already succeeded, but the American 16-bit console war had not yet truly begun. Nintendo was dominant, but challengers were gathering. Motion control looked like a futuristic possibility. Portable color gaming existed as an Epyx prototype. Publishers were filling Nintendo’s booth with games that would soon become remembered parts of the NES library, while other projects shown only in sales sheets would vanish before reaching a store.
For four days in Las Vegas, the future of video games existed in dozens of competing forms.
Some of them became history.
Others became what might have been.
