This Timeline shows major developments in computing, consumer and entertainment electronics through the 20th Century and into the early 2000s, before the widespread availability of electronic images


Clicking on any highlighted topic link in the Timeline below will take you to the relevant Picture Story -  archived images with some background from words that I wrote at the time.

Apologies for fact that the posted pictures are of deliberately compromised quality and heavily watermarked, but this is necessary to prevent commercial piracy. Some of the originals are probably now unique so potentially valuable. Be assured though that all the originals have been/are being scanned in high quality (600 dpi) without visible watermarking, and safely stored for legitimate use.

See the Copyright Note.

The Timeline is continually being updated, as more Picture Stories are added. I have pictures relevant to most entries but because the project was initially being supported by a grant from the Royal Television Society, priority for digitisation has so far been given to TV and video. This only scratches the surface of what's available. If anyone wants to help preserve it i.e. save the archive from being junked when I shuffle off mortal coils, please Contact Us
