What it used to be called:
Title cards quietly disappeared.
In the 1920s, the new kind of movies with built-in soundtracks were called talkies.
Once it became obvious that sound was here to stay, talkie was supplanted by movie, and silent movie designated the old-fashioned style.
An early use:
"Nobody can prophesy with any accuracy as to the effect the spoken movie will have upon the silent movie." John Gallishaw, Twenty Problems of the Fiction Writer, 1929
