Who? Ronnie DeVoe, Bobby Brown, Johnny Gill, Ralph Tresvant, Ricky Bell and Michael Bivins
Known for: setting the foundation upon which all boy bands would be built
Guided by Maurice Starr, New Edition released a string of super-happy pop music in the early '80s, which was probably the only time you could talk about junk food and romance in the same song. ("Popcorn Love" and "Candy Girl" were hits.) Apart from cavities, they also spawned the hip-hop supergroup Bell Biv Devoe, and, of course, Bobby Brown.

NEW KIDS ON THE BLOCK
Who? Jordan Knight, Joey McIntyre, Danny Wood, Donnie Wahlberg, Jonathan Knight
Known for: Hangin' tough. (Duh!)
The Boston-bred boy band was created by New Edition impresario Maurice Starr, who sought to create a white version of the group. After stumbling with their first album (remember "Popsicle?" It's O.K., no one does), the group scored a massive hit with "Please Don't Go Girl," from 1988's Hangin' Tough – and then went on to be the first teen act to score five Top 10 hits from one album. Guess you could say they got the Right Stuff. (We know: rim shot.)

Who? Depends on the year. Because they were ...
Known for: kicking out members once they turned 16!
The Puerto Rican boy band is famously known for launching the career of Ricky Martin, who joined the group in 1984. Although they rarely had crossover success on English radio, the group continued to record well into 2007.

Who? Nick Carter, Howie Dorough, Kevin Richardson, Brian Littrell, A.J. McLean
Known for: restarting the boy band craze in the late '90s with their No. 2 single, "Quit Playing Games (with My Heart)" – and going on to set records with Millennium, which sold 1.13 million copies during its first week of release in 1999.
They had all the essential elements: A cute one (Nick), a bad one (A.J.) – even a sensitive one (Brian), etc. Add that to infectious pop music confections helmed by Swedish impresario Max Martin, and the Backstreet Boys sold out arenas in the late '90s.

Who? Joey Fatone, J.C. Chasez, Lance Bass, Justin Timberlake, Chris Kirkpatrick
Known for: breaking Backstreet's record by selling 2.42 million albums during No Strings Attached's first week of release in 2000 – and they're still the record holder.
The five-man group started in Backstreet Boys' shadow, but thanks to killer synchronized choreography (cough, get the name? cough) and a charismatic frontman that God Must Have Spent a Little More Time on, 'NSync came out the clear winner of the Great Boy Band War of the new millennium.

Who? Scott Robinson, Ritchie Neville, J Brown, Abs Breen and Sean Conlon
Known for: bringing the U.K.'s burgeoning boy band fever Stateside in 1998 with their Top 10 single, "When the Lights Go Out."
5ive enjoyed a brief – but bright – moment in the spotlight in 1998 when they scored a pop hit with "When the Lights Go Out." Fickle fans soon fell for U.S.-bred boy banders, but they'll always have the NBA: their single, "Slam Dunk (Da Funk)" – seriously – was chosen as one of the NBA's theme songs.

Who? Drew Lachey, Nick Lachey, Jeff Timmons, and Justin Jeffre
Known for: having tribal tattoos, muscles and sweet, sweet harmonies
A rare quartet in the fab five world of boy bands – even rarer? They weren't created in a lab by a music producer – the foursome idolized Boyz II Men over boy bands. They were renowned for their brand of wedding dance-ready swoony ballads ("I Do (Cherish You)" and "Because of You.") And, of course, Nick + Jessica 4-eva.

Who? Devin Lima, Rich Cronin, Brad Fischetti
Known for: getting sick from Chinese food
Originally called the Lyte Funky Ones, LFO shot to fame in 1999 when a demo song, "Summer Girls," began getting radio play. The song included cheeky pop culture references to New Kids on the Block, New Edition, Beastie Boys, Macaulay Culkin and most famously, girls who wear Abercrombie amp Fitch. The song paved the way for a follow-up hit, "Girl on TV," inspired by Jennifer Love Hewitt, who went on to date late singer Cronin. Recently, they've resurfaced on the Internet, when it became known that Fischetti enjoys live-Tweeting his visits to abortion clinics.

Who? Lil' Fizz, J-Boog, Raz-B, and Omarion
Known for: bringing the phrase, "You got served," to the masses.
The L.A. foursome were only together for a brief period – 1998 to 2004 – and in that time, scored several hits with their RampB-flavored singles like "Uh Huh" and "Bump Bump Bump." But it was their starring role (yes, all four) in the No. 1 2004 movie You Got Served, where the singers showed off their skills as members of a dance crew.

Who? Ashley Parker Angel, Jacob Underwood, Erik-Michael Estrada, Dan Miller, Trevor Penick
Known for: being the first boy band to be created on a reality show, Making the Band, in 2000.
It was Y2K, and everyone wanted a piece of the slickly styled pie. And that included ABC, which launched Making the Band, a pre-American Idol reality show that awarded the winning group with a contract with boy band Svengali Lou Perlman's Transcontinental Records. O-Town were the winners, and released a self-titled album in 2001 – and the confusingly titled single, "Liquid Dreams."
