A great new feature in the iTunes 11 update that came out last year is “iTunes in the Cloud”. This allows you to listen to or watch any music or videos you have ever purchased with your iTunes account, even if they aren’t on your computer. In other words, movies and TV shows you purchase don’t have to take up valuable hard drive space. You can simply stream them! If they aren’t showing up in your iTunes library, you may need to enable “Show iTunes in the Cloud purchases” in iTunes preferences.
