I had a friend who operated a mobile disco service, and considered himself to be quite “with it” on the internet. He wasn’t bad, as he was perfectly capable of setting up a hosted domain and coding a rudimentary HTML page complete with every flashing and marquee effect the W3C had made available. An early adopter of internet advertising, he had posted his URL on his brand new vehicle INSTEAD OF his phone number.
His business pretty much evaporated overnight. For two reasons. One of which was that it was 1997 and no-one that seemed to require his services owned a computer, let alone a modem. Secondly, the URL on his van had omitted all the non alphabet formatting... it said along the lines of httpwwwmobilediscocouk.
