Twitter has announced a major expansion of its self-service ads platform, taking it from 33 countries to more than 200 (in other words, pretty much everywhere). The company launched its first Twitter ads for small and medium-sized businesses in April 2013,
and says it has since built a community of 100,000 active advertisers on the social network. The company has been investing heavily in its advertising business, in an effort to start seeing the kind of revenues – on mobile in particular – that have fuelled Facebook’s growth in recent years. Twitter ads have also become a more popular marketing channel for music companies of all sizes, sitting alongside Facebook and other targeted platforms.
