Every major North American league has a similar service (except the NFL), but the local blackouts make it a non-starter for the vast majority of the viewing audience. Football is more cable-cutter friendly because local games are almost always put OTA, so it's a matter of setting up an antenna if you don't want to pony up for cable. There are services that try to do an end-run around local blackouts, but that doesn't really apply here (since the goal is to have a 100% legal, approved means of watching the games live online).
