My family had Southwestern Cable... I don't believe we got MTV until October of 1982. The reason I think that is because I came home from an all-day experience at Jack Murphy Stadium to see The Who, Loverboy and John Cougar... Well, I missed most of John Cougar...
When I arrived home from the concert, it was pointed out to me that MTV was now on.
Since I have been watching videos on Los Angeles stations for a while, I don't recall what the first video I saw on MTV was. I do remember a lot of stuff that I would have never heard on the radio or likely even seen the album in the store because they were pulling everything out of anywhere they could find videos.
I do remember this one - it was a weekend binge of MTV and this song was on probably every other hour. The video looks like a different edit than what I remember...
