Ten years ago, Walt Disney Co, having fended off a hostile bid from Comcast, had to make a case why it was better off as an independent company. Disney’s shares have soared more than 250 percent since. Now, Time Warner Inc Chief Executive Jeff Bewkes faces a similar moment of reckoning after rejecting a bid for $85 a share from Rupert Murdoch’s Twenty-First Century Fox. Bewkes and other top brass will be under pressure at a meeting with analysts and investors next Wednesday to show they can repeat Disney’s magic.
