Reality TV shows are a guilty pleasure for many people, whether they care to admit it or not.
For decades, reality series have given viewers memorable villains, epic couples, and plenty of shocking moments.
There is also no short supply of different kinds of reality shows, from competitions to makeovers. While some don't last too long, there are others that become so popular that they remain on TV for years, providing numerous seasons of enjoyment.
With the return of "Fear Factor" on MTV on Tuesday, July 17 at 10 p.m. ET, here are the longest-running reality TV shows of all time.
"Cops" (1989 to present)
Paramount Network's "Cops" has been on air consistently since 1989. On the show, real-life cops travel with cameras to give viewers an inside look at what the occupation entails, from high-speed pursuits to drug busts and robberies.
Biggest stars: Each episode highlights a different law enforcement officer from across the country.
"The Real World" (1992 to present)
When "The Real World" first aired on MTV in the '90s, the idea was to follow several young people living together in the same city, experiencing the same things that typical youths are forced to confront — like religion and sexuality. The first season took place in New York City, while the most recent season (season 32) took place in Seattle, Washington.
Biggest stars: One of the most successful stars from "The Real World" is Jamie Chung, who is now an actress. Chung had a recurring role on season three of "Gotham" and currently stars as Blink on FOX's "The Gifted."
"The Challenge" (1998 to present)
MTV's "The Challenge" has been part of the network since it first aired in June 1998. Each season, familiar faces from other MTV shows (like "Are You the One?""The Real World," and "Road Rules") and new hopefuls complete tasks with the goal of getting the cash prize at the end of the competition.
Biggest stars: In November 2017, MTV launched "The Challenge: Champs vs. Stars," which featured previous champions facing off against celebrities. Stars on the show included Shawn Johnson, MTV's Matt Rife, rapper and actor Romeo Miller, and NFL player Terrell Owens.
