I have a clock radio that looks a little bit like a TV set
As for filmstrips and records, my high school had record players and separate slide projectors to show the slides. There'd be a "beep" to signal the kid running the projector to advance the filmstrip. One time the guidance dept was showing some silly filmstrip in the auditorium and some of the kids could fool the projector operator (by making a beep sound) to advance the filmstrip. This throwing the record soundtrack and the images out of sync, and towards the end the projectionist would run out of filmstrip before the record would finish.
