Keighran participated in the development of tvOS, the software that runs on the fourth-generation Apple TV. tvOS marked a huge step forward from software on previous Apple TV set-top boxes, introducing Siri support and a full App Store. According to Keighran, it also incorporates search and discovery elements that he created with Chomp.
In the tvOS development hierarchy, Keighran worked under Bill Bachman, who oversees Apple's media apps. Bachman reports to Robert Kondrk, Apple's vice president of iTunes content, who reports to iTunes chief Eddy Cue. Going forward, Keighran plans to create his own "iconic company," but says the decision to leave Apple was difficult.
While Keighran wouldn't give Re/code behind-the-scenes details on Apple's television development plans, he says Apple "looked at many different ways of delivering an awesome TV experience."
