Brad Adgate, director of research at Horizon Media Inc., talks about News Corp.'s bid to take full control of British Sky Broadcasting Group Plc and the probe into alleged phone hacking at Rupert Murdoch’s News International.   News Corp.'s 7.8 billion-pound ($12.4 billion) bid for BSkyB faces a review by the top U.K. competition authority that will take at least six months as the probe widens. Adgate speaks with Mark Crumpton on Bloomberg Television's "Botttom Line."
