Twitter announced its latest financial results last night, reporting revenue of $250m and a net loss of $132m for the quarter, up respectively from $114.3m and $27m in Q1 last year. Twitter averaged 255m monthly active users (MAUs) during the quarter, up 25% year-on-year, including 198m mobile MAUs. Just as with Facebook, mobile is what’s driving Twitter’s business: its revenues included $226m of ads, with mobile accounting for 80% of that. Meanwhile, Twitter’s data-licensing business generated $24m of revenues. “We had a very strong first quarter. Revenue growth accelerated on a year over year basis fuelled by increased engagement and user growth,” said CEO Dick Costolo, who said Twitter has more plans for its data business. “We’re going to continue to invest in scaling our syndication capabilities to include new ways to distribute our content. As we do, there’s significant opportunity for us in leveraging the widely distributed characteristic of public tweets,” he told analysts. How soon that plus ads can drive Twitter into the black remains to be seen.
