An excerpt from the article 15 facts about StarCraft

Real-time strategy, abbreviated as RTS, is a type of computer game that allows players to take ad hoc action without waiting for their turn. It is a genre that promotes rapid decision-making skills, in which the consequences of choices are immediately apparent.

The term “real-time strategy game” was first used in 1992 by Brett Sperry, who was responsible for the production of Dune II, released under the banner of Westwood Studios (later absorbed by Electronic Arts).
