Have you ever thought about how many things have become obsolete in your lifetime? I just read an interesting article here that talked about several things that have disappeared over the past ten years, or at least have certainly decreased in use amazingly quickly. For instance, VHS movies and VCRs , travel agents, wristwatches, maps, newspaper classified ads, encyclopedias, film cameras, fax machines… and unfortunately, the handwritten letter. Most of those are still around here and there, but get a lot less use than they used to.
I had to think of public phone booths–we rarely see those anymore.
What else can you think of that has disappeared?
