What's particularly amusing is that there were two WT articles, the first stating that "generation" does not include babies from that time, then the second stating that the "generation" does include babies.
WT October 1 1978, page 31
"Thus, when it comes to the application in our time, the 'generation' logically would not apply to babies born during World War I."
WT May 15 1984, page 5
"If Jesus used "generation" in that sense and we apply it to 1914, then the babies of that generation are now 70 years old or older. ... Some of them will "by no means pass away until all things occur"."
Of course this is all water under the bridge since time ran out even for babies, so the latest idea had to be bubbled together in a cauldron:
WT April 15, 2010, "Holy Spirit’s Role in the Outworking of Jehovah’s Purpose". para 13 - 14:
"How, then, are we to understand Jesus’ words about "this generation"? He evidently meant that the lives of the anointed who were on hand when the sign began to become evident in 1914 would overlap with the lives of other anointed ones who would see the start of the great tribulation."
Now this is a very surprising conclusion to come to, considering the mouthpiece of Jehovah had already firmly refuted, rejected and clearly buried any notion of an overlapping generation, just a few years prior:
WT October 15, 1988 page 4 "The Sign — Are You Heeding It?"
"Might it be, though, that the sign could occur over the span of many human generations? No. The sign is to occur during one particular generation. The same generation that witnessed the beginning of the sign will also witness its climax"
