Facebook made waves recently by pushing Microsoft aside by taking over its own display-ad selling functions.
AOL finished its fourth quarter with $176.4 million in display ad revenue, a 3 percent year-over-year drop, though its domestic display ad revenue grew 1 percent to $151.7 million, the first time the company had year-over-year growth in eight quarters.
Meanwhile, Google is expected to break the $1 billion mark in display ad sales this year, according to analysts.
