Microsoft doesn't appear to be slowing down in its quest to become a top player in digital advertising, announcing a new deal to sell contextual and paid search ads on sites published by The Wall Street Journal Digital Network.

The deal includes ads for The Wall Street Journal, AllThingsD.com, Barrons.com and MarketWatch.com. However, it does not change display advertising on Dow Jones properties, which is handled by DoubleClick.

Earlier this month, Microsoft announced a two-part ad deal with Edgar Online to serve ads on the financial information site in exchange for content to be used on MSN Money. Late last year, Microsoft landed a $500 million ad deal to sell for Viacom's digital properties.
