Twitter made more money from its mobile platform rather than its web platform “many times” in the last quarter.

At a recent conference hosted by The Economist Group in San Francisco, Twitter CEO, Dick Costolo, when asked about making money from mobile and the difference between Twitter and Facebook, said, “We’re borne of mobile”.

At a time when Facebook is trying to figure out how to make money from its 480+ million mobile users, Costolo said, “We have an ad platform that already is inherently suited to mobile, even though we launched our platform on the Web and only started running ads on mobile recently.”

Twitter’s 140 million or so active daily users now produce over 400 million tweets per day. Ads have been introduced into the timelines of users and Twitter also allows advertisers to post promotional tweets and conduct various marketing campaigns.

eMarkleter estimate that Twitter could trouser $260 million in 2012 and $540 million in 2014. Facebook, meanwhile, enjoyed earnings of over $3.7 billion in 2012. Whatever Facebook is working on in terms of monetising its mobile user base, it had better be good. The whole digital world is watching the efforts of the planet’s ‘smartest hackers’. No pressure then.
