The head of the Spanish-language television network Univision said on Monday that Comcast Corp’s plan to buy rival Time Warner Cable Inc could be “bad for Hispanic audiences.” Univision President Randy Falco said on a conference call with media analysts that the proposed $45 billion deal, which would bring together the No. 1 and No. 2 U.S. cable providers, was a “cause for concern.” “We are hoping at the very least there is that scrutiny and potentially much tougher restrictions added to the existing consent decree (prompted by a 2011 deal) that will protect Comcast competitors such as Univision who are serving minority communities in particular,” said Falco. Falco stopped short of asking the Justice Department and Federal Communications Commission, which are reviewing the deal to ensure it is legal, to block it outright. On the call, Falco said a primary worry was that Comcast, with its range of movies, television shows and sports shows, would be reluctant to carry networks that it did not own, such as Univision.
