Dive Brief:

• Twitter will pass Yahoo in digital display ad revenues for the first time this year, a new survey from eMarketer indicates.
• The survey estimates Twitter will have $1.34 billion in 2015 digital display ad revenues, compared to Yahoo's $1.25 billion.
• Both are dwarfed by Facebook, which will receive an estimated $6.82 billion in digital display ad revenues this year, and Google, which will pull in an estimated $3.52 billion.

Dive Insight:

The overall numbers look particularly ugly for Yahoo, whose digital display ad revenues are expected to stagnate over the next several years while its competitors gobble up market share. Facebook's revenues are expected to surpass $10 billion annually in 2017, with Twitter's share growing to $3.54 billion.

By then, Twitter and Facebook will own more than a third of a $37.3 billion market, eMarketer estimates.
