Online news and lifestyle site Buzzfeed is taking over HuffPost in a deal that brings together two of the most high-profile digital media firms.
This comes as digital media firms have struggled to draw online advertising dollars away from tech giants such as Facebook and Google.
In recent years, Buzzfeed and HuffPost have both shed staff. In May, Buzzfeed closed its newsrooms in the UK and Australia and slashed staff pay.
Buzzfeed chief executive, Jonah Peretti, who co-founded HuffPost will lead the combined business.
The two firms will also join up for advertising and sharing content, a partnership they said would “create new revenue opportunities”.
HuffPost rose to prominence during the George W Bush presidency as a site for liberal bloggers, many of whom contributed for free.
Buzzfeed made its name creating content like listicles and quizzes, which drew young audiences. It also brought on reporters for its news site.
