By Renee Maltezou ATHENS (Reuters) - Greece awarded new broadcasting licences on Friday in a politically controversial step to cull the number of television channels operating in an industry that authorities say is mired in mismanagement and corruption. Prime Minister Alexis Tsipras's left-led government has said the move will help regulate the sector, but the media says it will curb free speech and shut down stations, putting thousands of people out of work. Skai TV won the first license, allowing it to stay on air.
