Click on a company on the list, and you'll see people on your network who work at the company, along with other information.
CNNMoney, a unit of Time Inc, is the first company to take advantage of a new Javascript platform that LinkedIn introduced in October designed to integrate LinkedIn content across the web.
LinkedIn followed that move with share and recommendations widgets for websites and apps trying to integrate their content with LinkedIn. The former lets users share links they like while the latter is designed along the lines of Facebook's "like" button to offer the thumbs up for companies and products that users find favor with.
