Facebook is a social networking service (SNS) company founded in 2004 and headquartered in the U.S., which boasts one of the largest user bases in the world. Facebook was initially launched as a university social networking site, and it is recommended that users register for an account using their real names. For this reason, Facebook has recently seen an increase in group activities at schools, job hunting activities, and business use by companies and other organizations.
In 2012, Facebook acquired Instagram, a photo-based social networking service, for approximately $1 billion, which became a hot topic. Instagram has grown to become a mainstream social networking site among young people, partly due to the fact that it mainly uses photos and not text.
