Theorysonic Pyramid was launched on January 4, 2000, in El Kadsre with the price of $199. It has 4 player controllers, CD-ROM, DVD-ROM and a USB output for saving data, downloading content, playing multimedia and backup, while its controller has two analog sticks, a digital pad, four action buttons, two action triggers, built-in speakers and a built-in Page orientation color LCD screen. The Pyramid is the first and only game console to gain access to the web with the customized version of the Star Web browser built-in the console. It has similarities to Sega Dreamcast.
The sales declined following the popularity of most Portosic devices, more powerful consoles, and mobile gaming. It failed to outsell PlayStation 2 and Xbox 360. In 2006, no new Theorysonic home video game consoles released following lackluster sales, instead of focusing on work Portosic, TheoryPhone, and TheoryTablet devices and TS-UGOS computers for gaming. Over 17 million units sold worldwide during its lifespan. The console finally discontinued on April 30, 2011.
The Theorysonic Pyramid has over 400+ games.
