Google Inc. is being sued over accusations that it overcharged advertisers who use the Web search giant's paid search advertising program, which accounts for the vast majority of Google's revenue. The proposed class-action suit, filed on August 3 in State Superior Court in Santa Clara, California, accuses Google of charging in excess of advertisers' "daily budgets," under which Google allows an advertiser to limit how much it spends each day.
