Are ranked ballots already used anywhere?

Municipalities

A number of American cities use ranked ballots (called ranked choice voting or instant run-off voting) for some or all aspects of their municipal elections, including Berkeley, California; Cambridge, Massachusetts; Minneapolis, Minnesota; Oakland, California; Portland, Maine; San Francisco, California; San Leandro, California; Santa Fe, New Mexico; St. Paul, Minnesota; Takoma Park, Maryland; and Telluride, Colorado.

A number of other American cities have adopted or voted in favour of ranked ballot elections, which are now awaiting implementation.

In Britain all British mayors are elected with ranked ballots.

Canadian Political Parties

Canadian political parties have always used some form of runoff system to choose their leaders and to nominate the local candidates.  Recently, all of Canada's parties have decided to use ranked ballots to choose their leaders.  This change was made to boost internal democracy within the parties, allowing all members to vote - not just those who attend the convention.

The NHL

The National Hockey League uses a ranked ballot to choose its Hart, Norris, Calder, Lady Byng, Selke, Vezina, and Jack Adams award winners every year - with points awarded based on where each player has been ranked.  The National Basketball Association uses the same system to choose its top player awards as well.

The Academy Awards 

In 2010, the Academy Awards adopted ranked ballots to choose Best Picture.  This was done to avoid a situation where a movie could "win" with only 20% support in the Academy.

Canadian Sports Writers

In journalistic circles, the Canadian Press uses a ranked ballot for picking the Lionel Conacher Award, for Canada's male athlete of the year, and the Bobbie Rosenfeld Award, for Canada's best female athlete of the year.
