In the episode "Goodbye, Toby" Season 4 : Ep. 14, Michael Scott is in his office downloading mp3's on his computer. The camera clearly show him doing this through Amazon. Not iTunes, and Not an amorphous non brand.

I found this to be very amusing because it was not too long ago that NBC and Apple had their falling out. Now I can not confirm if it is a slight against iTunes and to say so would be purely speculation but with their bad history it makes me wonder.

There is another completely harmless explanation so I will also put it forward. It is possible that they sold this as a product placement add spot and amazon won the bid which would have no personal drive behind it. Whichever is the case it was interesting to see and I wanted to share it.
