I can only tell my experience. From 1976 to 1995, I went from door to door telling people that this generation will by no means pass away before the end will come. These are people who (are of an age to appreciate what was going on say, 10 15 yrs old in 1914) saw the fulfillment of jesus prophecies as per Matthew 24 (and more importantly 1914). It was consistently high lighted by the organisation that it must be SO CLOSE as they are old folks.
1995 article says that this generation is now figurative e.g. "in my father's generation" which is tottally non specific. It can be any time. This is a major change as after this article the preaching work lost urgency, the prophecy lost its power and it made a laughing stock of the wts and all who sincerely believed their version of truth.
