Apple has added several content channels to the Apple TV, including Watch ABC, Crackle, and Bloomberg. Crackle, a Sony service, lets you watch a number of TV shows and movies without a subscription. Watch ABC, meanwhile requires you to register your cable provider before you can watch full episodes. Currently, customers with AT&T U-verse, Charter, Comcast XFINITY, Cox, Google Fiber, Midcontinent Communications, Optimum, and Verizon FiOS can all be verified.
Bloomberg, in addition to its on demand video, is yet another move by the Apple TV into live content. Selecting Live TV from the rotating carousel of options or the Live TV tab will let you watch the program currently airing on the channel live. There is also a wide selection of on demand video as well.
Apple also added KORTV, a Korean content provider. This channel provides access to a number of Korean programs, and you can pay $5.99 for even more content.
We now also have some insight into how Apple TV apps are built. The developers behind the Bloomberg app said that they were given an SDK by Apple, which they then used to build an app for the Apple TV on top of Bloomberg's backend infrastructure in about five weeks.

The channels should appear on your Apple TV soon, and do not require a software update.
