During his tenure at ABC, the network began targeting programming toward younger viewers, who are most sought after by advertisers. ABC and Moore believed that demographic would be their ticket to the top.
"Probably his greatest legacy is that he changed the whole basis on which television time is sold, and thus, how television is programmed," TV historian Tim Brooks told the Los Angeles Times. "ABC basically introduced us to the concept of demographics. And ever since, we in the TV industry have been appealing to 18- to 49-year-old viewers."
Moore was also instrumental in developing the ABC Sports division, which won several Emmys for "ABC's Wide World of Sports" and Olympics coverage.
He hired sports producer Roone Arledge, who would become a legend, and helped create "Monday Night Football."
