Phonovision

1926 | October 5 – John Logie Baird applied for a patent for “Phonovision” – a system for recording and playing back #television images on 78 rpm phonograph discs.

By September 20, 1927, Baird had successfully transferred an image of his “Stooky Bill” doll to a 78 rpm disc.

On that same day, he applied for separate patents for his experiments with radar and fibreoptics.
