The US Emmy Awards are to become more competitive among performers, following a decision by organisers to combine leading and supporting acting categories for long-form programming.
Next year, the categories will be called outstanding actor in a mini-series or TV movie and outstanding actress in a mini-series or TV movie.
The field will be expanded from five to six nominees when they are introduced.
Last year, the outstanding TV movie and mini-series combined into one award.
Popular series such as Downton Abbey and films made-for-TV are likely to be most affected by the new format.
