Video Games 5

My sister and I got the FIRST video game for christmas in the 70s it was called pong. For those of you who are not old enough or old enough and have blanked it out.... this was pong.  A control board with two knobs and on the screen two lines that moved up and down knocking a blip back and forth that made a sound like sonar on a sub. I'm sure all you Wii users are now green with envy.
