With the baseball playoffs in full swing, Apple has released a new ad aptly titled "Game Changer". The new ad features the MLB At Bat application that features score checking, live pitch-by-pitch updates and streaming video highlights. MLB At Bat has also seen a recent price reduction, but word to the wise, it's only good through the end of 2008. It might be a good time for MLB to take a cue from other apps and offer it free for the duration of the 2008 playoffs. You can view "Game Changer" along with other iPhone ads at Apple's website.
