Actually the video game console came out first, if you're talking about people having a PC in their home. The Atari 2600 came out in 1977 and the Colecovision followed in 1982. That was before people were getting computers in their homes for the most part, unless they were wealthy. And technically, Bill Gates hadn't gotten PC's up and going yet. PC refers to a non Macintosh system. In reality the Apple II was before the PC.
So technically it's the other way around. PC's wouldn't be here without consoles.
