Internet services entity AOL Inc has announced three acquisitions, including technology blog TechCrunch as part of an effort to bolster its content offerings.
The offer of $50 per share is a premium of 17.4 per cent to AOL's Monday close.
Their move follows an activist campaign by hedge fund Starboard Value LP, which is pushing Yahoo to consider a deal with AOL and unlock Yahoo's valuable stakes in Asian Web companies.
Google Inc is expected to command more than a third of the world's $140 billion digital advertising spending this year
Yahoo Inc plans to spin off its 15 percent stake in China's Alibaba Group Holding Ltd, responding to pressure to hand over to shareholders its prized e-commerce investment valued at roughly $40 billion.
The valuation was more conservative than the $15 billion some analysts had expected for the social media phenomenon, potentially attracting investors who might consider the money-losing company's listing price a better deal, with room to rise.
