Looks like it is genuinely rotary dial design. Those aren’t buttons, they are holes. The text is on the black background, the clear plastic above it has holes cut out. There’s quite a bit of thickness to that plastic and it’s some distance from the black backing. Looks very much like a rotary phone looked, though understandable that most folks haven’t seen one up close.




Another perspective.
Once upon a time, it was pretty normal to watch something and not be able to pause or rewind. It was perfectly expected that you might not get every single word and you didn’t really think twice about it, just like you don’t think about how you miss some words in real life.
But now, we can pause, we can rewind. We can get exactly what was said and we get preoccupied with making sure we understand every single word. So captioning becomes even more critical.
