Apple followed up the on their Tuesday Apple TV announcement with another yesterday. As of Wednesday March 25 the CNN Go channel is available on all Apple TVs. It is always good to have more channels, but in this case you must still have a cable or satellite TV subscription.
I checked my Apple TV this morning and the CNN Go channel had been added to the lineup. I am glad to see Apple is adding channels, but there are many others I would rather see.
