The PDA is a central device in S.T.A.L.K.E.R., the post-apocalyptic first-person shooter series set around Chernobyl, where it stores the player's map, tasks, contacts, and incoming messages from other stalkers. The notification sound therefore became familiar to anyone who spent time in the Zone, signalling that new information had arrived without interrupting play. As clips from the games spread on video platforms, editors began lifting the short alert for their own work, and it has stayed popular because it is instantly recognisable, very brief, and carries a built-in sense of incoming news.
