Santa Clara, Calif.--Yahoo! Inc. has introduced a suite of b-to-b e-marketplaces aimed at technology industry executives. The Yahoo! Industry Marketplaces will initially include electronics, IT software and IT hardware marketplaces. The idea is that Yahoo!, already a favored information destination for tech executives, can compete as an e-marketplace destination as well. "Millions of business purchase decision makers are already using Yahoo! to search the Internet for industry news, gathering information and purchasing products," said Shannon Ledgers, VP-general manager.
