Information theory was originated by communications engineers in telephone Laboratories (partly 1928, €hanon 1948), their interest being tone problems of how quickly and accurately one can send messages over not sq tel ephone ltnes . From thts expe i ment they devel oped the tnf°o ma— tton theor'y as a means of dt scusstng suchlike prob\ ems .
