Report: Twitter Ad Revenue to Hit Nearly $1 Billion Next Year

Twitter's global ad revenue is expected to hit nearly $1 billion in 2014, according to a new estimate from eMarketer.

The researcher upped its estimates for Twitter's ad revenue this year and next based on greater-than-expected demand for Twitter's mobile ads. eMarketer now expects that Twitter will generate $583 million in ad revenue in 2013 and $950 million in 2014, up from a previous estimate of $545 million this year and $808 million next year.

"The upward revision comes as advertisers have shown more interest in spending money on mobile advertisements on Twitter, and as recent audience figures from multiple research sources analyzed by eMarketer have suggested Twitter's reach is improving," the report says. eMarketer also attributes some of the increase to the launch of Twitter's API last month
