Google is said to consider bidding for Yahoo's core business, Bloomberg reported, citing a source. Verizon Communications, which has been rumored to consider bidding for Yahoo, plans to make a first-round bid for the Internet giant's web business next week, Bloomberg reported.

AT&T, Comcast and Microsoft are not bidding this time, Bloomberg said on Thursday. Time Inc. is still evaluating a bid, while private equity funds Bain and TPG are also planning to make a run at the business, the report added.

Yahoo said it would explore strategic alternatives, including selling its main Internet operations, earlier this year after scrapping a long-time plan to spin off its stake in Chinese e-commerce giant Alibaba Group Holding.
