I worked in a photographic shop for a lot of years, when I started we sold Standard and Super 8, 16mm. Home video cameras where just coming in and had a camera with a tube that didn't like point highlights, a separate recording VHS or Beta machine to be worn on your shoulder, a battery life of about 20 minutes.. and cost upwards of £2000. We had shelves and shelves of 35mm film, Colour, B&W, Slide with a few 110, 126 and latterly Disc stuff and a 2x6ft run of shelving just for printing paper...we used to stock up the shelves to groaning full levels on a Saturday morning because that was always going to be your busiest day... and now there's smartphones and wireless uploads...
In the end the boss's son, who as a baby was brought in to be introduced to the staff as 'the newest addition to the family' was the man who made me redundant, just like all the tech matured, came and went, so did I!
