NBC sucks. The worst thing they could have done is send YouTube a C&D letter. Viral marketing can be defined as: Marketing phenomenon that facilitates and encourages people to pass along a marketing message. Without that marketing it wouldn’t have become popular. Which meant it wouldn’t be on iTunes. Does anyone else realize the material from Lonely Island (the guys who came up with it) was created under a Creative Commons license? I thought that was what made them so neat in the first place. NBC, you used to be cool…
