AI/ML has somewhat continuous research going all the way back to the First AI/ML Boom of the 1960s and the Second AI/ML Boom era of the "Lisp Machines" [1] in the 1980s. Depending on who you ask the current AI/ML Boom is something like third or fourth wave, and yeah some of that depends on where you fit Deep Blue and/or Watson in the timelines (or even if you bother at all to count them, given all the other comments here on how Deep Blue/Watson have always been PR maneuvers more strongly than technical lines in the sand).
