Internet auction site eBay has bought StumbleUpon, a website that recommends other websites, for $75m (£38m).
EBay has $3.5bn in cash and has been on a spending spree
The deal means eBay will get access to almost 2.5 million registered users, who recommend sites to each other.
Users get search results that are based on their profiles, which the site says gives them more relevant results than a regular search engine.
EBay had $3.5bn in cash last month and has been on an acquisition spree buying firms such as Shopping.com and StubHub.
StumbleUpon was founded in 2001 by three Canadian software engineers in Calgary.
It is free for users and generates revenue through advertising, although users may pay an annual fee to avoid seeing any adverts.
StumbleUpon's founders and managers will become eBay employees and eBay's Michael Buhr will become its general manager.
