The trend of cable television customers dropping the service will slow down soon.  Pop culture professor Bob Thompson says there's a population of young people in his college classes who have never hooked up, so they won't be dropping it.

“If I asked them to raise their hands and asked how many will go home that night to a room that's connected to cable,” Thompson says, “I would guess that maybe 10 percent will raise their hand -- if that.”

He says we didn’t have an alternative to cable 30 years ago.

“In 1985,” he explains, “you got cable because it was the only way you could get MTV, and CNN and ESPN and Nickelodeon and Disney.”

For now, the number of households dumping cable TV is growing, choosing services like NetFlix, Hulu or network websites for shows and movies.
