Linkedln does not rely heavily on targeted advertising but generates revenue from other sources. Identify other sources of revenue that Linkedln uses and explain how each contributes revenue.

Founded in 2002, Linkedln is the premiere social network for professionals, offering a comprehensive platform that stresses career progression and business services rather than updates for family and friends. Linkedln is far smaller than Facebook, but many high-powered professionals are members, including Fortune 500 business execs who rely on the service to expand their personal networks, identify career opportunities, recruit talent for their companies, and share information.
