William J. Bell is the creator and executive producer of the extremely successful soap operas The Young and the Restless and The Bold and the Beautiful.

He started his writing career on As the World Turns, working under the legendary "Queen of Soaps," Irna Phillips; Phillips' other protegee at the time was Agnes Nixon. Bell co-created Another World with Phillips in 1964.

In 1966, he was hired as head writer of the then-struggling soap Days of Our Lives. Bell was credited with the show's initial surge of popularity. He stayed as head writer until 1975.

In 1973, he created The Young and the Restless. Although slow to rise in the ratings, Y&R was credited of breathing new life into the daytime serial, with its brightness, humor and cutting-edge storylines. Bell guided Y&R as head writer from 1973 until stepping down in 1998, the longest tenure of any head writer in soap opera history. Y&R has been the highest-rated soap on the air since 1988.

In 1987, he created The Bold and the Beautiful, which was known for its glamorous look as it was set in the fashion industry. It followed Y&R and has been a ratings success as well.

He is married to former talk show host Lee Phillip Bell , who co-created Y&R and B&B with him. Their three children, Bill Jr., Bradley, and Lauralee, are all involved in their parents' soaps in some capacity.
