An observation I've made is that people who fall into the "baby boomer" generation generally have cable with some packages. Gen X, probably has cable... but Gen Y sees very little value in cable, and is highly likely to cord cut.
For example, in one of my groups of friends there's a sample of about 12 people between ages of 20-32... and not a single one of them has cable. My sister, who's in her mid 20s, has cable because her husband is a big sports fan. I can think of 4 other people in their mid 20s who are also big sports fans, who decided to STILL not purchase cable, and get their sports content from sports bars, and various online sources.
For reasons, I can really only speak for myself, since I haven't asked each of these younger people why they don't like cable... but for myself, I hate that the content isn't all "on demand". I think that the idea of having to watch a show at a certain time, or record a show, when it's not live content, is completely absurd. I find the user interface slow to navigate, and lacking options. And for the cost of the service, the amount of commercials is unacceptable.
If I had to put a number on how much money I think cable is worth to me... it'd be negative. With the very large amount of commercials, I actually feel they should be paying ME to sign up for the service, not the other way around. Perhaps tiered based on how much commercial content I watch... so when I see that they not only think I should be paying THEM for watching their commercials, but that they think I should be paying them A LOT of money to do so.... It feels like a bad joke.
