As much as I hated NBC, they had a show "The Today Show" that produced much more revenue than Wimbledon. Easy business decision for them.
ESPN has the luxury of having ESPN and ESPN2 which are sports based channels, and all ESPN has to do is worry about booting off Sportscenter to another channel or if they use both they still have ESPNNews.
I think NBC should've utilized NBCSportsNetwork more than they did, but it was Versus back then. Versus just turned into NBCSN in January.
