Spanish-language Univision is the most-pirated U.S. broadcast network on YouTube, according to TubeMogul, which monitors network usage on the video website. TubeMogul said Thursday that Univision shows have been pirated 583.75 million times. That compares with 289.07 million times for Fox, 260.30 million for ABC, 127.33 million for CBS and 120.89 million for NBC. (NBC makes the most determined effort of any network to keep clips of its shows off YouTube.) David Burch, TubeMogul's marketing manager, told Advertising Age that much of the Univision program viewing can be attributed to the telenovela Cuidado con el Angel. "If you remove the show, Univision would be the third-most-pirated network, below Fox and ABC," he said.
