From the 1950s through the 1980s, reality television programming was a rarity on the schedules of the Big Three networks. It was more of a novelty that piqued the interest of the viewers for a few months or a few seasons, then was relegated back into the shadows while scripted shows dominated the airwaves. It wasn't until the very end of the 1980s, when FOX premiered COPS, that reality-based programming became a prime-time staple.
It stayed that way for several years. Then, just like that, it all changed, thanks to one show that premiered in 1992. With a simple program on a fairly new cable channel, reality programming went from television rarity to huge success. So much so that, in a few short years, it spawned various direct copies and variations of its concept on both the over-the-air and cable networks. By the early 21st century the airwaves were filled with more reality programming than scripted works, garnering the ire and the joy of many a long-time television viewer.
And, it all began on a network primarily known for its music videos and Pauly Shore.

The first reality show contestant I learned to hate was Puck from the San Francisco season of MTV's The Real World. This was actually before people went on reality shows just to be on television and become some sort of celebrity. Oh, what innocent, fun times those were (and I'm serious - the first few seasons of The Real World were quite good).
