Twitter raising funds at $7 billion valuation: WSJ

Microblogging sensation Twitter has discussed the prospect of acquisition with Internet titans Google and Facebook, the Wall Street Journal said Thursday.

Twitter is close to raising up to 100 million dollars in new funding in a deal which values the hot micro-blogging service at one billion dollars, The Wall Street Journal reported Thursday.

Microblogging sensation Twitter is expected to rake in $150 million in advertising revenue this year, according to a study published Monday.

Twitter, which has fended off several buyers, intends to remain an independent company and is not considering going public at the moment, chief executive Dick Costolo said.

Twitter announced on Tuesday that it has acquired BackType, a San Francisco-based startup that helps publishers measure the impact of their social media use.

A fresh infusion of investment cash pushed Twitter's market value up to 3.7 billion dollars on Wednesday with the number of people using the microblogging service climbing to 175 million.
