If you look at the songs, most of the hits were written by the best writers of the day: Carol King & Jerry Goffin, Neil Diamond, Tommy Boyce & Bobby Hart. The musicians, for the most part, were known as The Wrecking Crew, and they played on all the big hits of the day, from The Beach Boys to the Fifth Dimension. The songs would have been hits by anyone, but they had the added benefit of a hit TV show for the marketing. That was a key discovery. The music industry found out there was a TV audience for young music. Not just Mitch Miller or Lawrence Welk. That discovery would lead to more TV shows aimed at promoting young music. The Midnight Special. Don Kirshner's Rock Concert. In Concert. All added to the longtime favorite American Bandstand. Kirshner was the music man behind the Monkees, and ten years later he would have success again with the rock band Kansas.
