I think it has been at least that long since MTV had a music video.
This one's pretty good.

Not quite. For a few days after 9/11, they seemed to realize that showing people whining on Road Rules might be a tad inappropriate, so they went back to the "let's show music videos for most of the day" format. Lasted about a week, IIRC, and then we went back to Billy and Debbie yelling at each other over who had to wash dishes in their million dollar condo.
I think the last time they really showed videos on MTV is when they axed Headbanger's Ball. Around about that time, The Real World premiered.
