In 2003, the Intellivision 25 and Intellivision 15 direct-to-TV systems were released by Techno Source Ltd. These are an all-in-one single controller design that plugs directly into a television. One includes 25 games the other ten. These Intellivision games were not emulated but rewritten for the native processor (Nintendo Entertainment System compatible) and adapted to a contemporary controller. As such they look and play differently than Intellivision. In 2005 they were updated for two-player play as the Intellivision X2 with 15 games. They were commercially very successful altogether selling about 4 million units by end of 2006.
