LinkedIn has been trying to increase the mobile advertising it displays. Last quarter, the "marketing solutions group," which includes traditional advertising, accounted for 27% of LinkedIn's revenue. Pulse's app competes with Flipboard, Google Currents and some other lesser known names in the battle for eyeballs. One competitor, Zite, was purchased by CNN in 2011 for $20 million.
Pulse has added some new features that allow its users to share with Facebook, Twitter, Google+ Flickr, YouTube, Instagram and Tumblr right from Pulse. LinkedIn has also been adding features to its service including customized news feeds for users, which would seem to fit perfectly with Pulse.
