In a move to align Internet advertising businesses controlled by CMGI Inc. , Engage Technologies Inc. will buy Adsmart and Flycast Communications Corp. in a stock deal worth about $$2.6 billion, the companies said on Thursday.

Consumers handed an estimated $$30 billion over to Internet sites last year, a sign that a lot of people have lost their fears about shopping online.

Ameritrade Holding Corp. , the No. 6 U.S. Internet brokerage, on Wednesday posted a smaller-than-expected loss for the fiscal first quarter and revenues more than doubled, boosted by a successful advertising campaign.
