CNBC Originals airs in-depth look at Facebook

CNBC Africa correspondent Lester Holt will present a comprehensive look at how Facebook, with half a billion users, is affecting society in ways most people are unaware of. The insert, titled The Facebook Obsession, provides the story behind the rise of the largest social media site in the world, told through the company's founders, friends and foes.

From a girl who is reunited with her birth mother with the help of Facebook, to a woman who lost her job because of her online postings, The Facebook Obsession examines how the site is fundamentally altering American life for better or worse; even the White House and many police departments have their own Facebook pages.

Holt explores the intense privacy debate that Facebook has provoked, and explains the business model that has turned a dorm-room venture into a multi-billion dollar enterprise.

The Facebook Obsession airs Monday, 17 January 2011 at 11pm CAT.
