LOS ANGELES (MarketWatch) -- Google Inc. GOOG, -1.66% may enter a potential bidding war with Facebook Inc. FB, -3.30% for Israeli mobile-app developer Waze Inc., according to an anonymously sourced Bloomberg News report late Thursday. Earlier news reports had tipped Facebook as conducting advanced talks to buy Waze for between $800 million and $1 billion. The Bloomberg report said Waze was seeking more than $1 billion from Google, and may decide to stay independent and raise financing instead. Waze, based in Israel with a Palo Alto, Calif., U.S. headquarters, makes apps which offer user-generated traffic and navigation information.
