Where did teenagers come from? Filmmaker Matt Wolf is exploring that question in his new documentary "Teenage."
From the end of the 19th century and into the first half of the 20th, the idea of a unique youth culture was being developed, and a population that once went straight from childhood to adulthood now had another stage entirely. Wolf's new documentary looks at the invention of adolescence.
Nowadays, youth is stretched out and the teenage years were invented because suddenly there was time to grow up where there hadn't been before. Wolf says it was the dawn of a completely new era in human culture.
He joins The Takeawy to explain when teenagers first became a distinct group and how they are different today.
