In just 3 years, it’s estimated that Twitter’s global ad revenue will have increased by nearly tenfold. In 2011, the popular social networking service raked in 139.5 million dollars, while the newest projection from eMarketer is for $950 million in global revenue in 2014.
While the revenue number is skyrocketing, the overall growth of Twitter ad revenue is not surprisingly retarding over time as it matures. The near $1 billion ad revenue in 2014 will signal a 63% growth from 2013, down from the 102.2% estimated growth this year.
The biggest revenue driver on Twitter’s ad growth is undoubtedly mobile. Last year, Twitter saw just $138.4 million in mobile ad revenue, a number that will surpass $550 million in 2014. In 2015, eMarketer expects that mobile revenue will extend over $800 million, making up over 60% of the overall revenue:
Last year, the United States made up 90% of the overall ad revenues, a number that is expected to drop to 76% by 2015. Non-US ad growth is expected to increase more than 11x from $28.8 million to $319.2 million.
