Wall Street Journal: Yahoo has quickly gone from beleaguered to belle of the merger ball. But one potential buyer remains the suitor to beat. Verizon plans to submit a first-round bid for Yahoo in time for the April 18 deadline. Other possible bidders include the U.K.’s Daily Mail, CBS and IAC/InterActiveCorp. Given Verizon’s heft and the intensity of its recent focus on becoming a major player in mobile advertising, the telecom giant seems most likely to emerge victorious.
