“I explained to the broker that the idea of “push” technology was first called “selective dissemination of information,” or SDI, and, to my knowledge, had first been proposed in 1961 – yes, 1961 – in an article in the journal American Documentation by an IBM computer scientist by the name of H.P. Luhn (1961). He worked out the idea in considerable detail; the only key difference was that the old mainframe computer would spit out informative postcards to be mailed to customers, rather than sending the information online – since there was no “online” to use in those days.”
Which reminds me both that
innovation comes only from a deep understanding of the problem (otherwise you can fall into the trap of re-invention.)
those who do not learn from history are doomed to repeat it.
