This was posted on Tumblr, which is generally known for its short attention span, and the blogger has a large contingent of younger fans, who may not be interested in reading about Youtube and would prefer to continue viewing cute cat gifs.
That being said, I didn't realize that YouTube was funding original channels! I'm reminded of the talk Dan Harmon (creator of the television series "Community") gave regarding the death of television/the Internet as a new platform for stories [1]. The majority of people already consume television shows on the internet, I'd love to see a larger shift towards an internet-only tv series model.
