CID is an Indian Hindi language crime drama created by B. P. Singh that premiered on Sony Entertainment Television in 1998 and ran for over twenty years, becoming one of India's longest running television series. Its investigation scenes, led by ACP Pradyuman with officers Daya and Abhijeet, became deeply familiar to viewers. The show's serious background music and theme are now reused online as a shortcut for detective work, with fans pairing the CID song with door breaking jokes, mock interrogations and everyday mysteries that need an exaggerated sense of importance.
