Angry Birds launched in 2009 from Finnish studio Rovio Entertainment and became one of the first huge mobile game hits, built around flinging birds at green pigs in fragile towers. Its stretch, launch and crash noises became as recognisable as its characters, so clips of the raw effects spread to YouTube edits, soundboards and meme videos. The no music version is especially popular with editors because the isolated effects can sit under new footage without clashing with another soundtrack, keeping the joke tied to the original game.
