Viacom had ulterior motives when the demanded YouTube remove some 100,000 video clips last week. The company is planning on creating a Comedy Central portal where you can post clips of your favorite South Park, Colbert Show, Daily Show, as well as MTV favorites. It will be fascinating to see if Viacom can can compete with YouTube, or just become a footnote in Internet history. My bet is that the company that brought us Jon Stewart and The Colbert Report can pull this off -if (and a big if) they create channels for non-branded user-generated videos. The first mover advantage only lasts so long -just ask Yahoo! Posted by Casey Kazan.
