LifeStreet Buys Facebook Advertising Network from Rival SocialCash

Third-party advertising networks have been running ads in Facebook applications for years. But between Facebook’s own self-serve advertising units, stricter platform rules and a host of new companies, the market has gotten more competitive. Today, one of the newer entrants, an established online advertising company called LifeStreet, has purchased the Facebook advertising network of one of the earlier ones, SocialCash.
