The communicator was the wrist-mounted gadget used by the teen heroes of Mighty Morphin Power Rangers, the American series that premiered in 1993, to receive calls and summon each other for battle. Its electronic chirp became one of the most recognisable audio signatures of nineties kids television, carried across later seasons and anniversary revivals of the franchise. In the streaming era the two-second beep found a second life on soundboards and in meme edits, where a burst of retro nostalgia sells a punchline. Today it circulates in reaction clips and throwback compilations as shorthand for the original team assembling.
