I think the closest thing back then was a fax, which could transmit monochromatic documents. Halftone (grayscale) fax was invented by Arthur Korn in 1902, enabling newspapers to send/receive photographs via telephone. That used mechanical parts, electronic ADCs were developed in the 1920s.
As for the newest word in the acronym: The word bit only appeared in 1946, the word bite (machine word) probably shortly after, spelled with a Y since 1956.
