From those of us that remember MTV when the "M" stood for music, and wonder why they stop playing videos, Kennedy was on local radio with an answer.
In the early years, viewers were willing to watch all sorts of videos even from music styles or artists they may not like, but as the channel matured and then started playing the same videos over-and-over from a single genre, viewers would turn the channel on, become frustrated at the singular offering and not tune back for a few hours in hopes of seeing a video they liked. Management figured that they needed to find a way to keep viewers tuned in for at least 30 minutes at a time so they wouldn't lose out on revenue dollars from commercials and since MTV could no longer keep viewers tuned in, they were forced to switch to produced shows. They also had noticed that radio station websites were offering videos that a person could view instantly, so their video channel was no longer viable media.
So, long story short, Radio (and MTV hitching their wagon to a singular genre) killed the Video Channel. Not the other way around.
