Another news of that heavy-spending habit is now making the headlines.

“The acquisition will enhance Yahoo’s consumer and advertiser offerings – Polyvore will strengthen Yahoo’s digital magazines and verticals through the incorporation of community and commerce, and together Yahoo and Polyvore will power native shopping ads that drive traffic and sales to retailers”, Yahoo said in the statement, as mentioned by Business of Fashion.

While Polyvore, a visual search engine for clothing and outfits, generates revenue through affiliate marketing, Polyvore’s active users produce tons of content on the site by arranging images of clothing into outfits and sets of outfits. Described as a way to “discover and shop for things you love in fashion, beauty and home decor”, the site was founded in 2007 by ex-Yahoo engineers.

The acquisition, which hasn’t closed yet, will mark a homecoming for three of Polyvore’s co-founders, Jianing Hu, Guangwei Yuan and Pasha Sadri.

Polyvore, the brainchild of three ex-Yahoo companies, started in 2007. Yahoo didn’t disclose the price in its announcement on Friday. The accord, reported last week, comprises about $40 million in retention payments, as indicated by the people, who asked not to be identified because the information hasn’t been revealed. Broadly, Polyvore will accelerate Yahoo’s Mavens growth strategy (mobile, video, native, social) through its strong offerings in social, native, and mobile.

The CEO of social shopping site Polyvore has been swallowed up – company and all – by Marissa Mayer’s Yahoo. The company added that the combination Yahoo’s industry leading digital content with Polyvore’s expertise in community and commerce has outstanding potential.

Once the leading portal on the Internet, Yahoo is now struggling to ramp up its mobile and advertising businesses after being outpaced by the likes of Google and Facebook.

Yahoo sure is buying up businesses, and there’s no sign of them slowing. In fact, the firm spent more than $900M on “acquihires” that include Flurry and BrightRoll past year. However, it is certain that its expense side of the balance sheet will be bigger in the third quarter as the firm continues to invest heavily in growing market share.
