The idea bombed everywhere it wasn't government-subsidised, because by the time videotex was practical the installed base of personal computers could hook up to {time-sharing} services and do the things for which videotex might have been worthwhile better and cheaper.

Like the {gorilla arm} effect, this has been a cautionary tale to hackers ever since. See also {vannevar}. [{Jargon File}] videotex: n. obs.
