NBC no longer supporting Apple iTunes

NBC was apparently one of the biggest supporters and most important companies who was on iTunes - They had tons of hit shows (most notably, to me atleast, The Office) on the service, and not only will they not provide new shows on the service, but they'll also remove any shows as well that were already on it... This really sucks for me, becasue I just got an iPod Video, and was really looking forward to buying The Office (even though I already have the DVD's).
