Ahead of the Bell: Web conference in San Francisco

SAN FRANCISCO (AP) ? Executives from leading Silicon Valley companies are expected to speak Monday as a three-day Web conference opens in San Francisco.

A senior executive from Yahoo Inc. is among the scheduled speakers. Ross Levinsohn, head of Yahoo’s North American operations, makes an appearance amid talks of a sale of the beleaguered Internet company.

Levinsohn has been mentioned as a possible successor to former CEO Carol Bartz, who was fired last month following more than 2 1/2 years of financial lethargy.

Also at the annual Web 2.0 Summit is Mark Pincus, the founder and CEO of online game maker Zynga Inc., which has filed for an initial public offering of stock.

Monday’s lineup also includes chief executives from online marketplace company eBay Inc., online software company Salesforce.com Inc. and chip-maker Intel Corp.

The annual event brings together some 1,000 senior executives from the technology, media, finance, telecommunications and entertainment industries. This year’s conference focuses on the impact of data in a networked economy.
