I dont see the need for the "NBC" text in the DOG, surely the peacock is iconic enough to stand on it's own?

Absolutely, but NBC has alternated DOGs with both yes and no NBC text. Between 1997 and 2002, NBC had a transparent peacock as DOG; it added the NBC word mark by 2002; with the HD switch and the More Colorful era arriving, the peacock became again standalone as DOG (alongside the move to its current position).
