In the early 80s, William Shatner became a pitchman for Commodore Computers. And in 1982, the same year that "Star Trek II: The Wrath of Khan" hit theaters, Captain Kirk himself appeared in a number of TV commercials and advertisements like this one promoting the new, ultra-affordable Commodore VIC-20.
The VIC-20 is considered to be the first low-cost color computer, thanks to its $299.95 price tag and its large color display. The VIC-20 became the best-selling PC in 1982, and it was reportedly the first computer of any kind to sell more than 1 million units. But when Commodore introduced the 1983 Commodore 64, the VIC-20's sales plummeted until the model was discontinued in 1985.
