Hora Certa was the time announcement segment on Radio Transamerica in Brazil, where a short branded sting signalled the exact time between songs and programmes. This 1990s version became memorable for listeners who heard it daily at home, at work and in cars across the country. Long after regular radio listening declined, clips of old broadcast cues resurfaced in nostalgia posts, video edits and soundboards. The Transamerica sting survives because it captures a specific era of Brazilian radio in just a few seconds, instantly recognisable to anyone who lived through it.
