Pinoy Big Brother, often shortened to PBB, is the Philippine edition of the Big Brother reality franchise that has aired on ABS-CBN since 2005. Doorbell-style chimes are part of the show's house language, signalling arrivals, tasks and announcements inside the famous yellow house. Clips labelled with the show's name circulate widely among Filipino meme pages and fan editors, who reuse short audio moments in their own edits. The ding dong tone endures because it is instantly recognisable, easy to place over any entrance scene, and carries the nostalgic charge of reality television.
