NEW YORK ( TheStreet) -- Popular searches on the Internet Thursday include Moammar Gaddafi on reports the expelled Libyan leader has been killed.

The reports of Gaddafi's death are unconfirmed, though the Libyan rebel government is expected to give an official statement within hours.

Another popular search Thursday is Yahoo! ( KMI) as rumors swirl about potential buyers of the Internet company and their distaste for Yahoo!'s demands for confidentiality.

Yahoo! advisers informed those interested in buying the company this week of a "no cross talk" provision in a non-disclosure agreement that they must sign in order to gain access to the company's financial data, Reuters reported. The "no cross talk" provision is aimed at encouraging competition between bidders and gives Yahoo! more control over the process.

Potential buyers including private-equity firms have refused to sign the the nondisclosure agreement, Reuters said.

Groupon is another popular topic. The online coupon company is reportedly cutting down the size of its planned initial public offering.

Although the company filed to raise up to $750 million in its IPO in June, it now plains to raise less than that amount, with some estimating it plans to raise $500 million. Groupon's latest IPO filing also indicates that current shareholders no longer plan to sell stock in the offering.

Groupon reportedly plans to launch its IPO roadshow next week.

The chatter on Main Street (a.k.a. Google, Yahoo! and other search sites) is always of interest to investors on Wall Street. Thus, each day, TheStreet compiles the stories that are trending on the Web, and highlights the news that could make stocks move.
