History

Nintendo saw firsthand how successful videogames were in the late 1970s. They also saw the success the Colecovision, released in 1982, had with their own game, Donkey Kong, as a pack-in. Nintendo, who at the time was better-known for their playing cards, wanted to get into the console race. At first, they distributed the Magnavox Odyssey in Japan, before they decided to make their own console. Hiroshi Yamauchi, then CEO of Nintendo, wanting the Nintendo console to outperform the others, hired Masayuki Uemura to design it. At first, the console was supposed to be a 16-bit machine with a disk drive, and average for $75 USD. However, the price was too high due to component prices, and so they made an 8-bit system. The disk drive would be an add-on exclusively in Japan.

In the wake of the video game crash of 1983-1984, many said the video game console industry was quite dead and that Atari had killed it. While the American videogame market might have been in shambles, in Japan, Nintendo was enjoying a great success with its Famicom (Family Computer) system, released in 1983. In 1984, Nintendo wanted to bring this console to the States. Originally, Nintendo had been negotiating with Atari to have the Famicom released under the name "Nintendo Enhanced Video System" with Atari's name, because of the perilous market conditions of the time. But this deal fell through, and Atari decided to concentrate on the Atari 7800, leaving Nintendo to itself.

In June 1985, Nintendo presented the console at the CES to skeptical gamers. Nintendo was forced to promise to retailers that Nintendo will buy back all unsold consoles, since they were afraid that they might not sell. Nintendo released its system in the US in 1985, a decision that was to prove hugely profitable for the company. The system had first been test-marketed in New York, where its 100,000 systems sold out.

Treading carefully after the crash, Nintendo decided to release the system as an "Entertainment System" as opposed to a "Videogame System" (hence its name); it used "Packs" and not "Cartridges." If they had not done this, most retailers, seeing that the NES was a video game system and knowing the current status of video games, would not have accepted it in their store in fear of losing money. Nintendo drastically redesigned the casing of the Japanese Famicom: its playful red and white color scheme was muted to an A/V component grey, and the cartridge was made to be hidden inside the console when inserted (the Famicom's cartridges popped up from the top of the unit, much like the American Super Nintendo). These modifications served to make the unit much less "toy-like" in the eyes of its designers. Unfortunately, the revisions also had the side-effect of making the NES more prone to breakdown, as the loading mechanism became notorious for slowly failing, requiring gamers to use all sorts of methods of getting their games to turn on (like blowing on the contacts, half-seating the games, etc.)

Additionally, Nintendo created the R.O.B. (Robotic Operating Buddy), a plastic robot that connected to the NES and was moved around as part of an on-screen game, to unveil along with the NES at the Consumer Electronics Show of 1985. R.O.B was already dead in Japan (with only two games, Gyromite and Stack-up, ever released for it), but it would demonstrate the NES's technical superiority above other consoles of the time. Packaged with the NES were Super Mario Bros. and Duck Hunt.

The console could be bo ught with the ROB, a light gun, and three games for $249. The console with Duck Hunt and Super Mario Bros. only was sold for $199. Different packages came along as the NES went worldwide.

These games had proven themselves in American arcades, and the prospect of a home console powerful enough to handle arcade-perfect versions of them was cause for some excitement among gamers. Despite favorable reactions from both industry critics and early American testers, Nintendo had a difficult time selling stores and distributors on the idea of another videogame system, so they hired Worlds of Wonder (makers of Laser Tag and Teddy Ruxpin) to handle the NES's marketing. Worlds of Wonder was successful: the NES had sold over 20 million units in the US alone by the end of its production run.

Having Super Mario Bros. on the package meant success for Nintendo, who controlled the market with a 10 to 1 market share, due to the fact that many video games published by third parties went to the NES. The NES ended up outselling the Atari 7800 and the Sega Master System in North America.

However, the NES was not as successful in Europe. Many third party publishers went with the Master System instead of the NES in that market, and the NES wasn't sold in as many places. Nintendo was forced to get licenses to popular Master System titles. Nintendo would not have much success with the SNES in Europe either.

The NES was able to outsell the Master System in Australia, although by a slighter margin than it did in North America.

Nintendo re-released the NES as the NES 2 in 1993 with smaller red and white casing at $49, just in time for the Christmas season. The reason for the rerelease was because a lot of older Nintendo Entertainment Systems in the United States were dying due to bent connectors and dirt . Finally, after a full decade of production, the NES was formally discontinued in the U.S. by Nintendo in 1995. However, due to a continued interest on behalf of its fans, it has continued to thrive via a large secondhand market and a proliferation of ROM images.

The NES had survived for a long time, and many great games had been made for the said console. 50 million consoles and more than 350 million games had been sold in all. The NES is credited with resurrecting the video game market, and the video game market has not suffered a crash since.

The NES after 1995

The NES was in popular decline from 1991-1995, with the Sega Genesis and Nintendo's own SNES in North America eating away at its market share, and next-generation CD-based systems on the horizon. However, even though the NES was discontinued in North America in 1995, it had left the mark of many millions of game cartridges. The secondhand market - video rental stores, Goodwill, yard sales, flea markets, games repackaged by Game Time Inc. / Game Trader Inc. and sold at retail stores such as K-Mart - was burgeoning. Parallel to or perhaps because of this, many people began to rediscover the NES around this time, and by 1997, the games were becoming quite collectible.

At the same time, something else was happening: programmers who were also NES enthusiasts began to create emulators capable of reproducing the internal workings of the NES. When paired with a ROM image, a bit-for-bit verbatim copy (or dump) of a NES cartridge, the games could be played on a computer. ROMs and emulators were traded on various BBSs around the country, and as it became more popular and accessible, on the Internet. ROMs were hard to come by, and emulators extremely buggy - sometimes designed to play one specific game.

However, emulation provided access to many rare and hard to find games that otherwise would have been lost. This provided Nintendo enthusiast with a much wider selection than ever would have been imagined with the original console. Emulators also came with a variety of built in functions that changed the gaming experience such as built in Game Genies (an extra feature of the original console), and save states that allowed the player to save at an exact spot in the game and resume later at that exact spot (not possible with the old system).

On April 2, 1997, Bloodlust Software released NESticle 0.2 - an emulator that was considered highly stable, compatible, and easy to use by the standards of its day (the product, according to its creator Sardu, of "two weeks of boredom"). After this, emulators quickly became more refined and ROMs more easily available, which brought more people into NES emulation, which in turn served as a catalyst for further development.

Nintendo, did not take to these developments kindly; no other video game company has been as tenacious in its dedication to trying to wipe out ROM trading as they have. Nintendo claims (along with some NES fans themselves) that ROM trading represents nothing more than gratuitous piracy. Proponents of ROM trading argue that it is emulation that will preserve many of the great (while technically obsolete) games for future generations, outside of their more fragile cartridge formats.

The NES revival settled back down, to a degree, in 2000, after the secondhand market began to dry up or charge collector's prices, and finding ROMs no longer represented the challenge it had in the past. Still, developments continue, and the NES, alongside the SNES, appears likely to command throngs of fans for years to come. Publishers have released over 700 titles but no longer produce new commercial games. However, there is a strong independent community producing demos and games for the NES.

Nearly all classic computer and gaming systems have experienced revivals through emulation, incluiding Atari, Commodore 64, Sega, Game Boy, SNES, and even classic arcade games. This is due to the appeal of playing games and using systems in as close to the original format as possible.
