Our family has gone 100% subscription/ala carte for music, TV, movies, and radio.
We dumped Cox cable except for internet.
With a four year old son, and our low tolerance to be what I call "revenued on" by commercials we want to watch what we want and when without commercials. For these reasons subscribing to music and getting programming ala carte is perfect for us.
As for my four year old, I don't want him exposed to commercials, and I cannot control the content of TV or the timing without ala carte from iTunes or Netflix. This way we have complete control over what and when our boy watches.
Music/radio:
-Pandora-subscribed, we find all kinds of new music to listen to. Foreign, classical, rock by band or genre, we love it.
-iTunes, I put all of our CD's onto my Mac, and can stream it to any device via iTunes Matching and iCloud. Let me tell you, it's pretty cool to listen to your own catalog in a hotel two thousand miles away, your entire catalog.
-Radio: We either listen to NPR on an NPR player on our phones plugged into speakers, or I listen to radio stations on their websites streamed into speakers. There is no radio in the house, but I can listen to a rock station in Berlin, Germany or talk radio out of London, GB. Pretty cool.
TV/movies:
-Netflix: out go-to screen source. They have excellent original programming (House of Cards, Orange is the New Black) as well as a very good selection of TV shows and movies.
-Apple TV: If we just can't wait for it to show up on Netflix we rent or buy TV seasons. We are Walking Dead and Sons of Anarchy addicts so we get these seasons right away.
-Buy movies: I go to a used music store that is huge, Zia Records, in Tempe, AZ. Tons of used movies and CD's used for smokin' prices.
