New York -- AOL's once-aspiring Platform-A network has been going through a lot of changes lately after splitting with sugar daddy Time Warner. The company, like Yahoo, taking stock of its less profitable assets has announced the sale of “Buy.at,” the affiliate marketing firm it acquired two years ago, to London-based Digital Window for an undisclosed sum.

The buyer, London-based affiliate merchant Digital Window, which owns subsidiaries including Affiliate Window, one of the UK's biggest affiliate networks, said it plans to incorporate the buy.at network with its existing affiliate business, AffiliateWindow, price comparison site ShopWindow and content customizer ContentWindow for customers in the UK, USA and Scandinavia.
