Who Wants to Be a Millionaire first aired in the United Kingdom in 1998 and became a global television format, with the United States version launching in 1999. Its dramatic lighting and electronic score, composed by Keith Strachan and Matthew Strachan, made every answer reveal instantly recognisable. The correct answer sting is part of that original sound design, marking a safe move up the prize ladder. Clips and recreations spread through quiz apps, classroom games and online videos, where the sting now works as shorthand for getting something right under pressure.
