Pinterest is opening its Promoted Pins feature to all advertisers

Ben Silbermann, the CEO of Pinterest, laid out plans last year for how he intends to monetize the popular web service. As part of a beta program for this plan, a select few advertisers were allowed to put their promoted pins in search results and category feeds. A little more than a year later, Pinterest has announced that the results of the test have been promising, and that the company will be opening the service to all advertisers.
