So in case you missed it Wednesday, the MLB sent a notice to Apple that several podcasts in the iTunes store had infringed upon it's trademark. Which prompted Apple to remove them for the iTunes podcast directory. This led to several high profile podcasts being taken out of iTunes because of minor infractions that included team names in the subtitle and/or thumbnail images.
