According to a new forecast by eMarketer, Twitter`s ad revenue could more than double this year to reach $583 million.
This surge in ad dollars is largely powered by an increased interest in mobile advertising on Twitter. Mobile ad revenue is predicted to soar 123 percent this year and could account for more than half of Twitter`s total ad revenue.
The lion`s share of Twitter`s revenue is still generated in the United States. In 2012, only 10 percent of Twitter ad dollars were spent outside the United States. The company`s continued expansion of foreign sales operations is expected to bring this percentage up to 24 percent by 2015.
