Comcast Chief Executive Brian Roberts is swallowing his ego a second time. The controlling owner of the U.S. cable firm decided not to top rival Walt Disney’s $71 billion bid for some assets of Rupert Murdoch’s Twenty-First Century Fox. He also backed down from an aggressive tilt at the Mouse House 14 years earlier. Given the eye-watering price Disney is paying, Roberts and his shareholders should come out the winners. Instead, Comcast will focus across the Atlantic and attempt to win a bidding fight with Fox for pay-TV outfit Sky, for which Roberts has so far bid around $34 billion.
