NEW YORK (AP) — Google is expected to surpass Facebook in display advertising revenue this year, beating all other competitors with a 15.4 percent share of the U.S. market, according to a closely followed research firm.

EMarketer said Thursday that it expects Google Inc. to generate $2.31 billion in revenue from online display ads — the graphical advertisements people see on websites. Display ads are more lucrative than the text-based advertisements that appear next to search results and account for the bulk of Google’s revenue.
