In 1983, Nintendo released the Family Computer (or Famicom) in Japan. The Famicom supported high-resolution sprites, larger color palettes, and tiled backgrounds. This allowed Famicom games to be longer and have more detailed graphics. Nintendo began attempts to bring their Famicom to the U.S. after the video game market had crashed. In the U.S., video games were seen as a fad that had already passed. To distinguish its product from older game consoles, Nintendo released their Famicom as the Nintendo Entertainment System (NES) which used a front-loading cartridge port similar to a VCR, included a plastic "robot" (R.O.B.), and was initially advertised as a toy. The NES was the highest selling console in the history of North America and revitalized the video game market. Mario of Super Mario Bros. became a global icon starting with his NES games. Nintendo took a somewhat unusual stance with third-party developers for its console. Nintendo contractually restricted third-party developers to three NES titles per year and forbade them from developing for other video game consoles. The practice ensured Nintendo's market dominance and prevented the flood of trash titles that had helped kill the Atari, but was ruled illegal late in the console's lifecycle.
To make it easier to see a dark emoticon clearly for those that use dark backgrounds such as via Theater Mode, you could create a thin 1 pixel line of off-white (#F1F1F1 is the correct color code) around the edge of the emoticon shape. The reason for this specific suggestion is that this is the default background color of Twitch chat, so the outline will not be noticeable outside of any dark mode. This is not always necessary though, so use your own judgment and test it on a dark background to ensure quality.
