Twitter has said it had become profitable, disclosing that its live messaging service is carrying 130 million daily tweets, or short messages, from its members.
The US-based company, which has been one of the fastest-growing social-networking services, said 40 per cent of tweets are transmitted by mobile devices, typically smartphones.
“We’re making money,” chief executive Dick Costolo said in Barcelona at the Mobile World Congress expo, but gave no figures.
