Viacom is asking YouTube to remove more than 100K unauthorized clips from its site. "After months of ongoing discussions with YouTube and Google, it has become clear that YouTube is unwilling to come to a fair market agreement that would make Viacom content available to YouTube users," Viacom said. UBS views the move as a negotiating measure. "We think Google pays up now, in the early days, to establish its long-tem position. We think its an excellent use of capital, though it may pressure margins," the investment firm said in a note to clients.
