(Wall Street Journal) – MENLO PARK, Calif. — Facebook Inc. is widening its lead in the online display advertising market ahead of an expected filing for an initial public offering.
The social network’s share of the display ad market — or banner advertisements on the internet — grew to 27.9 percent for 2011, compared with 21 percent a year earlier, according to new data released Monday by research firm comScore Inc.
That puts Facebook far ahead of its closest competitor, Yahoo Inc., which had 11 percent of the display ad market, up only slightly from 10.9 percent in 2010. Trailing far behind are Microsoft Corp. and Google Inc., which both have less than five percent, according to comScore.
