Never Gonna Give You Up was released by Rick Astley in 1987 and became a worldwide pop hit. Two decades later, internet users began disguising links to its music video as links to unrelated news, trailers and downloads, creating the prank now known as Rickrolling. The joke spread through forums, message boards and later social media because the reveal was instant and easy to share. It remains popular because almost everyone recognises the opening within seconds, making it a reliable shorthand for a harmless online trick.
