History - 1920s?
The Washington Post says: "The birth date and birthplace of the VCR depend on how far back you want to look. Video recording technology itself dates to the early 1920s, but the company Ampex is credited with developing the first commercially viable videotape recorder in 1956. The machine was bulky, expensive and designed primarily for professional broadcasters." The article ought to have some reference to what video technology was possible in the 1920s. Presumably, since magnetic tape was not invented, it must have used a disk system? 2.31.164.0 (talk) 15:30, 20 June 2021 (UTC)

'One of the first tape recorder' under 'Analog video' should have an 's' appended to it. 2A02:C7F:9E3B:CD00:C135:2AF3:755F:A23D (talk) 07:56, 18 July 2021 (UTC)

Unnecessary spaced
What’s up with words beginning with 2 space bar clicks? Can we remove that? I don’t think it’s needed Very different name (talk) 11:10, 12 March 2024 (UTC)

Electromagnetic waves
The history section states that video is encoded using electromagnetic waves, with a link to electromagnetic radiation. This is not true in most cases as electromagnetic radiation is basically radio. Video transmitted by cables is encoded electronically. Video recorded on tape is encoded magnetically in magnetic particles. Early video was even recorded on film (Scophony), so the encoding had nothing to do with electromagnetism. Baird's mechanical TV system encoded the images mechanically, turning them into an electrical signal which would have then modulated a radio transmitter for transmission as electromagnetic radiation.

Video can be encoded in many ways but the one common factor is that the images are first turned into electronic signals, not electromagnetic waves (radio etc.), whether analogue or digital.

I have therefore changed the statement.
