Popping onto the scene in 1984, New Kids On The Block were considered the first modern boy band – though vocal groups of young men is, of course, nothing new (see: New Edition, Jackson 5, The Monkees and The Osmonds). The term wasn’t particularly common until the early ‘90s, when groups like Take That and East 17 caught on. Characterized by soulful ballads, dance-friendly synth-pop, and trendsetting style, boy bands spread rapidly on both sides of the Atlantic, melting the hearts of countless girl and sell tens of millions of albums along the way. Fronted by Robbie Williams and Gary Barlow, Take That had a total of 25 Top 40 hits in the UK alone. Irish Westlife (with Brian McFadden) and Boyzone (Ronan Keating) had great success in the UK as well, while the Backstreet Boys (Nick Carter) and ‘NSYNC (Justin Timberlake), dominated stateside. In the 2000s, as the boys turned into men, popular interest in the beloved and derided genre faded, but not before launching some adventurous solo careers and producing a hefty queue of songs that continue to captivate. Here are some of the biggest hits of the boy band era.
