This place is MASSIVE! I had no idea how long it would take to get through the entire thing! Honestly, you could spend the entire day there! I thought that we could take a couple of hours to look at everything, but talk about sensory overload! The entire downstairs has ALOT of information, but at the same time a lot of it is jammed into display cases and there is ALOT of foot traffic, so have patience and if you really want to see everything, hope you have time.
They also have this awesome display of the Pink Floyd album/movie "The Wall" and this cool video of how "video killed the radio star" all about MTV, it's short, but it's interesting information.
