According to Wired:
"Apple Computer has slapped Podcast Ready with a "cease and desist" letter, claiming that the terms "Podcast Ready" and "myPodder" infringe on Apple's trademarks, and that they cause confusion among consumers. The company has been cracking down on use of the word "pod" by all sorts of parties, even though its trademark is for the word "iPod."Will Apple succeed in aggressively defending the word "podcast" as its trademark? We'll see what happens. We may see a lot of different products and sites change their names.
