Doyle has brought her dynamic executive skills to this Viacom trio of brands, which have all risen to new heights under her leadership. MTV of late ranks among the fastest-growing cable networks, with four consecutive quarters of primetime growth, while VH1 has experienced 11 consecutive quarters of growth. At last year’s “MTV Movie & TV Awards,” Doyle made a historic shift by removing all gendered categories in the show. That carried over to the VMAs and every other MTV tentpole event. She also invited transgender military members to attend the show and walk the carpet while conversation surrounding their service was all over the news.
