Line 3:
When the [[single transferable vote]] (STV) [[voting system]] is applied to a single-winner election it is sometimes called '''instant-runoff voting''' (IRV), as it is much like holding a series of [[runoff voting|runoff]] elections in which the lowest polling candidate is eliminated in each round until someone receives [[simple majority|majority]] vote. IRV is often considered independently of multi-winner STV because it is simpler and because it is the most widely advocated electoral reform in the United States.
Outside the USA, IRV is known as the '''[[Alternative Vote]]''', '''[[preferential voting]]''', '''single-winner STV''', or the '''[[Thomas Hare|Hare]] System''', though there is room for confusion with some of these terms since they can also refer to STV in general. In the US, IRV is also known as '''Ranked Choice Voting''' ('''RCV'''), a term
Instant-Runoff Voting was invented around 1870 by American architect [[William Robert Ware]]. Ware was not a mathematician, thus never subjected his election method to any rigorous analysis. He evidently based IRV on the single winner outcome of the [[Single Transferable Vote]] or STV developed in 1855 originally by [[Carl Andrae]] in [[Denmark]]. It was introduced into [[England]] in 1857 by the [[barrister]] [[Thomas Hare]], where it earned public praise from [[John Stuart Mill]], an English philosopher, member of parliament, and employee of the [[British East India Company|East India Company]].
