A teen idol is a celebrity with a large teenage fan-base. Teen idols are generally young but not necessarily teenaged. Often teen idols are actors or musicians but some sports figures also have an appeal to teenagers. Some teen idols began their careers as child actors. The idol's popularity may be limited to teens, or may extend to all age groups. Many teen idols are targeted for adults for nostalgia purposes.There were teen idols before there were teen magazines, but idols have always been a permanent feature in magazines such as 16 magazine, Tiger Beat and Right On! in the United States, and in similar magazines elsewhere.
