Dulles, Va. - Unable to woo the company's largest shareholder, AOL on Monday extended its cash offer for Sweden-based online advertising firm TradeDoubler until March 14, the Associated Press reported.

AOL has offered $900 million for the company, but TradeDoubler's largest shareholder, Alecta, last month rejected the offer as too low.

Alecta, which owns slightly over 10% of TradeDoubler, has the power to block the deal, since it is contingent upon the approval of at least 90% of shareholders.

AOL has said that it doesn't plan to increase its offer. The proposed acquisition is part of AOL's strategy to boost its online ad revenue in Europe.
