Facebook launched 4 February 2004 on Harvard Campus
" Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered user of Facebook, though variations exist in this requirement, depending on local laws"(No reference in Wikipedia Article)
"Facebook held its initial public offering (IPO) in February 2012, valuing the company at $104 billion, the largest valuation to date for a newly listed public company. It began selling stock to the public three months later. Facebook makes most of its revenue from advertisements that appear onscreen."(No reference in Wikipedia Article)
I remember reading about the launch. Financial analysts were warning that "Facebook shares were overpriced for the IPO as Facebook revenue was too low" (reference) "The shares fell quickly in value"(reference) and "shareholders sued" (reference)
31 August 2018 I'll find the references at a later date. (KB)
