The Academy of Television Arts & Sciences has reversed a decision it made a few years ago and will implement a change in the Emmy Award categories this year. Variety reports that this year’s Emmys will include separate categories for movies and miniseries, after ATAS voted Thursday to retreat from the three-year-old category merger.

The story reports: “The board of governors’ vote approving the rules change was initiated after a petition from several constituencies within the TV industry, led by FX Network, home of the anthology series ‘American Horror Story,’ which is submitted as a miniseries; and 20th Century Fox Television, which produces that program.”

HBO, whose movies have been competing against miniseries since the categories were combined, also supported the petition, along with 30 network and studio executives, the story adds.

The piece notes, however, that even though “the programs will again be separate, awards for actors, writers and directors in the two genres will remain combined. As a consolation, however, the board also voted to expand the number of nominees from five to six, recognizing the breadth of quality work being done in the longform arena.”

One issue arising from the change is how the awards will be presented, given the desire to keep the ceremony manageable for its prime-time telecast. It’s likely that the two categories will rotate between the prime-time awards show and the Creative Arts presentation, which is scheduled eight days earlier, the story adds.

The change is happening because networks are once again producing limited or event series, especially after the success of miniseries such as “Hatfields & McCoys,” the piece notes.
