Label applied (in the UK at least) to the 1970s precursors of contemporary boy bands: groups created and promoted for purely commercial reasons with a target audience (or rather, a target market) of girls in the 10-16 age group, in (generally successful) attempts to recreate the hysteria that had greeted the Beatles and the Rolling Stones in the preceding decade but without any inconveniences like artistic pretensions, contentious politics or drug busts. The canonical teenybop group was a bunch of rather dimwitted provincial twenty-somethings with bog-brush haircuts who warbled cheap love songs to a boogie beat and were usually kept under high security conditions, managed by some Svengali figure whose primary challenge was making sure none of the band members went to bed with 14 year olds, and who usually skipped with the proceeds as soon as a record failed to make number 1.
Teenybop bands that should be forgotten include the Bay City Rollers, Slik and Kenny; the label was also applied to imported talent like the Jackson Five, the Osmonds and the Partridge Family and a few faded glam artists like Gary Glitter, Mud or Alvin Stardust.
