The latest update to Apple TV brings MLB.tv streaming to the device allowing you to watch both live and previous games (based on the package you subscribe to). The MLB.tv subscription costs $20-$25 per month.
Also new to Apple TV is streaming from the NBA for $65 or $100 depending on the number of teams you want to follow.
It's great to see new features added to the Apple TV. But I'm surprised to see that Hulu+ wasn't added. Would have made a great addition. Perhaps with the next update?
