“We came up with the pre-nomination Emmy window,” said MTV general manager Amy Doyle, executive producer of tonight's Tiffany Haddish-hosted awards show, which was pre-taped on Saturday. “We’re sort of assuming that celebrities will want to be seen during that time. They’ll want to be high-profile and top of mind as well as the TV production companies and movie studios.”
