Released in 1977, the Atari 2600 (aka Atari Video Computer System) quickly became a popular home video game console in the early 80's.
Adventure contained one of the first "Easter Eggs" in a game, where a programmer would leave a little treat to be found. Many arcade games were emulated for the system, and a highly anticipated version of
Pac-Man was a major disappointment. Aggressive marketing of this game and a game based on the movie
E.T.: The Extra-Terrestrial contributed to what is known as the video game crash of 1983.
Still, the games were fun.

Activision made quite a few decent games.
So, did you own one? What games did you have?
I still have the one my parents purchased in 1981; a six-switch with wood-grain panel. It still works. We used to have a lot more games than what's with it now. Here's a list of games I remember having:
