Usenet, which arrived in 1979, was beat by a precursor of the electronic bulletin board system (BBS) known as Community Memory in 1973. True electronic bulletin board systems arrived with the Computer Bulletin Board System in Chicago, which first came online on 16 February 1978. Before long, most major cities had more than one BBS running on TRS-80, Apple II, Atari, IBM PC, Commodore 64, Sinclair, and similar personal computers. The IBM PC was introduced in 1981, and subsequent models of both Mac computers and PCs were used throughout the 1980s. Multiple modems, followed by specialized telecommunication hardware, allowed many users to be online simultaneously. Compuserve, Prodigy and AOL were three of the largest BBS companies and were the first to migrate to the Internet in the 1990s. Between the mid-1980s and the mid-1990s, BBSes numbered in the tens of thousands in North America alone.[11] Message forums (a specific structure of social media) arose with the BBS phenomenon throughout the 1980s and early 1990s. When the Internet proliferated in the mid-1990s, message forums migrated online, becoming Internet forums, primarily due to cheaper per-person access as well as the ability to handle far more people simultaneously than telco modem banks.

Reddit is a social news website and forum where stories are socially curated and promoted by site members. The site is composed of hundreds of sub-communities, known as "subreddits." Each subreddit has a specific topic such as technology, politics or music. Reddit site members, also known as, "redditors," submit content which is then voted upon by other members. The goal is to send well-regarded stories to the top of the site's main thread page.

Managing social media isn’t a particularly lucrative profession yet, but it does serve a growing need for a lot of businesses. If you keep an eye out for job postings you might be able to nab a job promoting a company or brand on various social media services. A lot of those jobs are independent contractor positions, many of which you can work remotely. If you’ve got a lot of experience with social media beyond just being a user, though, you may be able to get hired to develop social media strategy. Telling businesses how specifically to approach their social media presence would very likely net you a nice income.
Social CRM (customer relationship marketing) can be a very powerful business tool. For example, establishing a Facebook page allows people who like your brand and the way you conduct business to Like your page, which creates a venue for communication, marketing and networking.
