Perhaps not the methods through which we learn, but the media through which we obtain information.
For example, I used to like watching documentaries on the television. However, now, I prefer to read online articles - for some reason I find them far more interesting than reading a book (except a really good O'Reiley book on something obscure like "PC Hardware in a Nutshell") or reading the newspaper.
I watch the news for half an hour a day - find out that Britney Spears cheated on Justin, some other famous person is going to prison for doing something naughty, some company has been swindling money out of people, and Dave is suing Mike for calling him an oboe when he was five.
Then, I fire up the computer, hit some forums, spread and gain some knowledge, following that I check out www.theregister.com for news that's ACTUALLY interesting.
I don't feel like going on anymore; time for somebody else's thoughts...
edit: Oh, one more thing - I think the point I'm making is that TV is increasingly providing pointless information that isn't of much use to anybody.
