(Reuters) – Verizon is the clear favorite in the upcoming bidding for Yahoo’s core Internet business, according to Wall Street analysts, in large part because the telecommunications company’s efforts to become a force in Internet content have gone relatively well under the leadership of AOL Inc Chief Executive Tim Armstrong. Verizon acquired AOL last June for $4.4 billion – its first big foray into the advertising-supported Internet business – and it is not yet clear how well the unit is performing financially.
