Never Gonna Give You Up was released by British singer Rick Astley in 1987 and became a worldwide number-one hit. Twenty years later it became the centre of Rickrolling, an internet prank that began around 2007 in which a misleading link or title promised one thing and delivered Astley's video instead. The joke spread through forums, social media and video platforms because it was easy to share and instantly recognisable. It remains popular today as a light-hearted surprise in memes, streams and edits, long after most viral jokes fade.
