No, this isn't a music video, but it's the song for your reference.
In 1985 Weird Al did a song called "Cable TV" which described the life-transforming power of getting a cable hookup. I still have it on cassette and I play it in my car to much enjoyment.
But my favorite part is the anachronistic bits. Whenever he does a topical song, he will exaggerate things to make them funny. Example: In "It's All about the Pentiums" he describes having a "flat screen monitor 40 inches wide" and a computer with "100 gigabytes of RAM."
But in "Cable TV," the 1985 exaggerations have already been surpassed. He complained about his Cable costing him a ridiculous "50 bucks a month" in 1985. Using the uber-cool Inflation Calculator, I can see this equals $98 a month in 2010, something that people regularly pay.
He also exults in having "83 channels of ecstacy." I think even the most basic package has this beat.
