Oct. 26 (Bloomberg) -- Portugal’s planned sale of state- owned broadcaster RTP-Radio Televisao de Portugal, as advertising revenue is dropping, may cause a potencial decline of about 60 percent in the revenue of its rivals, said Francisco Pinto Balsemao, chairman of broadcaster Impresa SGPS SA.

Balsemao spoke at a conference in Lisbon. The Portuguese government plans to sell RTP as part of the country’s external bailout plan.
