Last year my cable company added a Bloomberg channel. Bloomberg appears to be slightly better than CNBC, so I switched to watching Bloomberg.
Then I stopped watching them. I can't identify any new thoughts which caused me to stop watching, so it's hard to avoid the conclusion that I acted irrationally at some point. The best explanation I can come up with is that as long as I was following a fixed routine, the mental effort needed to abandon the routine prevented me from changing. Switching to Bloomberg was much easier because it didn't seem like much of a change, and didn't require admitting that I'd been making a mistake. But since I hadn't developed an attachment to Bloomberg, it was easier to stop watching it.
I've since given up cable/broadcast TV entirely, and use Netflix and Comedy Central's website as replacements. I'm quite satisfied with the change.
