Has Comcast bet against technology?

IN FORGING HIS media empire Rupert Murdoch never worried much about whether he was spending too much money. He thought it mattered more what businesses he was building. Such as, in 1989, a cash-haemorrhaging satellite broadcaster in Britain called Sky Television. Decades later Brian Roberts, chief executive of Comcast, an American pay-TV giant, proved Mr Murdoch right again. In October he completed a deal to buy Sky, a successor to Sky Television, for £30.6bn ($40bn).
