Walden stated that the network planned to commission and acquire more series from "independent" studios not co-owned with the Big Three networks, explaining that the vertical integration of the major broadcast networks (including Fox itself) with associated studios had limited opportunities for outside studios, and cited several top programs that were distributed by third-parties, such as The Big Bang Theory and This Is Us (produced by Warner Bros. Television and 20th Television for CBS and NBC respectively). There were also plans for Fox to acquire new pitches directly from their writers, and offer them to outside producers. As part of the transition, Fox aimed to gradually reduce the amount of scripted programming development coming from 20th Television, although stalwarts such as The Simpsons would remain with the network. Following the completion of the sale, network head Dana Walden became chairwoman of Disney Television Studios and ABC Entertainment. AMC president Charlie Collier succeeded Gary Newman as chairman and CEO of Fox on November 1, 2018. Newman was expected to temporarily remain with Fox in a transitional role, in order to oversee the corporate transition.

Fox also established a new in-house studio, Fox Alternative Entertainment, for investments in non-scripted formats. It is led by Rob Wade, while its first production was the second season of The Masked Singer (after season 1 was produced by Endemol Shine North America).Thursday Night Football finished as the second highest-rated series of the 2018–19 television season in the key demographic, behind only Sunday Night Football, while The Masked Singer finished tied for third with
