In January last year, Time Warner Investments, the corporate venturing fund representing media conglomerate Time Warner, led a $12m series B round for US-based social TV analytics firm Bluefin Labs.

GDGT has raised $3.7m in its seed and series A rounds from a consortium including AOL Ventures and venture capital firms Betaworks, Spark Capital, True Ventures and Lerer Ventures.

It would have an initial market capitalisation of about $438m, if it floated at $14 per share.

US-based antibody research company KaloBios Pharmaceuticals has raised $70m in its IPO.

Hearst Interactive Media and Google Ventures were involved in a $4m funding round for GoMiso in December 2011.

Inside Secure has about 15 backers including corporate venturing units from Samsung, Nokia, Qualcomm and Motorola.

If enough employees accept the tender offer to hit the $80m limit, BlackRock will own just less than 1% of Twitter, according to news provider Financial Times.

The final year figures for Intel sealed off another active year for Intel Capital, with 57% of the dollars invested outside North America.

Israel-based conglomerate SK Group has acquired Camero, a Motorola-backed radar-based imaging developer, for an undisclosed amount estimated in the tens of million of dollars, according to news provider Globes.
