This week’s podcast extra is about podcasts, but this story has its roots in the early days of rock 'n' roll. Alan Freed was a celebrity DJ on WINS in New York, famous for helping popularize the nascent genre through the 1950s. But, unbeknownst to his listeners, record promoters were secretly bribing Freed and other popular disc jockeys across the country for extra air time for their artists — in a rampant practice known as “payola,” which eventually caught the eye of regulators. In 1960, the Federal Communications Commission (FCC) outlawed payola, requiring broadcasters to disclose any payments received. However, members of the music industry would continue to blow the whistle on similar behavior in the decades that followed.

According to Bloomberg reporter Ashley Carman, a similar culture of pay-to-play is taking hold in the world of podcasting. Her latest piece is titled, “Podcast Guests Are Paying Up to $50,000 to Appear on Popular Shows.”
