Facebook has shelled out a total of $50 million to nearly 140 celebrities, media companies and video creators in an attempt to annoy...I mean "engage" Facebook users. Has anyone at Facebook ever thought that, if we wanted to see videos from any of those people, we would already be following them? Well that seems like money well spent. Facebook Inc. has inked contracts with nearly 140 media companies and celebrities to create videos for its nascent live-streaming service, as the social network positions itself to cash in on a lucrative advertising market it has yet to tap—and keep its 1.65 billion monthly users engaged. The company has agreed to make payments to video creators totaling more than $50 million, according to a document reviewed by The Wall Street Journal.
