In 1988, Broyles found critical success with the television series "China Beach". In addition to co-creating the show with John Sacret Young, Broyles also wrote or co-wrote several of the early episodes, and remained producer and creative consultant throughout the run of the show. In 1991, the Golden Globe-winning "China Beach" went off the air, but Broyles was well into production on his second television project, "Under Cover", a political espionage series following the adventures of husband-and-wife secret service agents, Dylan and Kate Del'Amico. The series was short-lived, and Broyles next adapted the Nigel Hamilton book, "J.F.K.: Reckless Youth", for a 1993 television mini-series of the same name starring Patrick Dempsey as the young future president.
