Pinterest app will start coming pre-loaded on Nook tablets along with Twitter and Facebook

Pinterest announced Monday that the company’s app will start coming pre-loaded on all Nook tablets, along with social apps like Twitter and Facebook (s FB). The partnership comes as Pinterest works to build its influence with businesses and has expanded to integrate with other products like Microsoft’s Bing image search results.

Nook representatives noted in the press release that Pinterest had been one of the most-requested apps for the Nook store, which allows customers to download games and social apps. Pinterest also fits with some other features of the new tablets Barnes & Noble introduced last fall: An improved magazine- and catalog-reading experience, and a “rip out the page” feature that lets users save pages from catalogs and magazines to a digital scrapbook.

Pinterest, long known for its innovative design, has been growing rapidly over the past few years, and just took in $200 million in a new round of financing  that puts that company’s valuation at $2.5 billion. A February Pew report estimated that about 15 percent of online adults use Pinterest, and the company has been stepping up efforts to provide businesses with analytics tools and specific landing pages just for them. Last week, Bing announced that users would now be able to pin images directly from the search function to Pinterest.

In February Barnes & Noble reported that Nook revenues for the third quarter were down 26 percent to $316 million, even though the company released two new tablets during the year. The company said it expects Nook Media, which it spun off as its own segment last year, to bring in revenues of $2.5 billion for fiscal year 2013.
