I get what people mean about how a la carte would probably be more expensive than packages, especially for those of us who watch sports. But someone had a good comment about this when I googled the topic. Music used to be like this. You had to buy an entire album or CD to get the 1 or 2 songs you like on many albums. Now you can pay for and download just the songs you want, and you can almost always buy at least half the album individually for less than the entire album package.
So why did this happen? Did the demand for music a la carte make it happen, or was it technology and piracy, where Napster or just borrowing a friend's CD to rip an mp3 or two cut into album sales? Finally the music people realized that selling individual songs was better than selling nothing at all.
Will the same thing happen with TV? There are a lot of free streaming sites, but they can be unreliable, plus they are illegal. It's tough to enforce though, and the providers and networks have to focus on not letting people advertise on public forums. I'm on a couple of sports forums where the mods delete any posts advertising free streaming because they have apparently been threatened by companies like ESPN and Cox. Eventually though, I see things changing, and even though ESPN may find only 25% or whatever the number of current subscribers will pay for the sports package, they will also get new subscribers who would pay a reasonable price for just sports.
If not, while I love watching sports, at some point I just won't pay. They can't keep raising the price on a decreasing number of watchers. Eventually they need to stop paying exorbitant prices for the rights to broadcast games, and in turn teams will stop paying nine figure multiyear contracts to players.
