On top of my display case I have an old 80's TV that I play vintage game commercials on from a DVD player. This comes in handy when people ask About things such as the Sega Master System and I can turn on the TV and, suprise, there is a Sega Master System commercial. Literally When I am showing off my collection people will sit down and watch the entire 20 minutes of game commercials.
if anyone knows a good place that they can be downloaded from let me know, I probably need to update my lineup. I tried to do the thing where you download them from YouTube but I could never get it to work.
