It was no longer written by the old established songwriters of Tin Pan Alley, but by young people. They helped to establish the new teen idols and wrote the so-called "teeny bopper songs", which "blend soft rock with pop ballad, is not explicitly physical and only hints at sexual interaction. The difference that the 70s' "Teeny Bopper syndrome" had with prior idol phenomena was that these new teen idols were directed at even younger girls, down to 15 years old, who were too young to have heard The Beatles and were not attracted to the new hard rock music of the time that their elder siblings listened to. This new market has a quick turnover potential and it boosted the benefits of many broadcasting companies. The teenybopper idol image is that of the young boy next door, with its key elements being self-pity, vulnerability and need. Their music is consumed by young girls, who collect posters and pin ups.
