Opera Software has agreed that Google Inc. will be the default partner for its mobile Internet browsers, Opera said on Thursday.

"Google will be the default search partner for the mobile browsers: Opera Mobile and Opera Mini," Opera Software ASA said in a statement. "Under the one-year contract, Opera will make Google Search a major part of the browsers home screen."

Oslo-based Opera Software is a tiny competitor of Microsoft in the Internet browser market, but the fast-growing part of its business is in browsers for mobile phones and other mobile electronic devices.
