In the early days of the WTS, resolutions played a different role than they do today. First, there were not that many members. Second, the door to door work was new to most of them. Third, many times these resolutions were distributed in the millions. Now think, how did so few members distribute so many??????? Not door to door. My details may be fuzzy but they distributed them through the newspaper service, much the way inserts today are distributed. Also, they paid newsboys to distribute them. It wasn't until the 1940's that the WTS started what we know as the "bible study program." People were warned through such whole distribution and were expected to seek out the JWs.
As more people came in, were trained in the indoctrination techniques of the WTS, one on one studies were more usual, the "magic" of the resolutions waned.
It has gotten to the point that JWs don't remember there was a resolution, let alone what it said. The WTS doesn't even print the content in their publications, let alone for distribution to the public.
Since 1945, the end of WW2, resolutions are rare, with the WTS recording the existence of only 10 or so since then let alone their content.
