Sounds like I left during the changing of the guard.
If there was one dominant theme to mark the witnesses from Franz era up through 95' it was the generation doctrine. With time eventually rendering the concept incoherent, the religion was bound to change as a result.
My gut feeling before I left around 04/05' was that witness leadership was quickly facing tough decisions about the future. Sounds like the changes have been made.
The JW movement, including the Bible Students for that matter, were always print oriented. Written publications were the center of their religious experience.
Being publication/print oriented, from my perspective, offered two distinct selling points for the faith:
1. Access to intellectual pursuits for the "common man", cultivating the concept of the armchair bible scholar. The JW publications of up through the 70s reek of Pseudo-intellectual jibberish. For anyone who found it convincing, it would be seen as an attractive alternative to Christianity's theologians, higher education, ect. The style provided the appearance of giving theological power back to the masses.
2. Comfort through simplicity. From the very beginning Russell's books were packaged as a set. The simplicity of providing "all your bible study needs in one location" makes selecting what to read a non issue. As an added bonus for the org, accepting the Watchtower as God's channel is the built in outcome of this convenience. Humans in general gravitate towards simplicity, so once you decide one of these books is true why not just accept the entire boxed set into your heart as your lord and savior.
From what everyone has written, it appears that there appears to a shift going on regarding the experiential features of group membership. The written word content is still there, but it appears the trend of simplifying the content continues. The tone of the magazines/books definitely got progressively generic from the 1980s through the 1990s compared to their historical material (founding through 60s). By the mid 2000's I was starting to think the content was just laughable. What does the Bible Really Teach? was the last publication I remember, which almost played as a joke publication of what a satirist would make pretending to be a Jehovah's Witness.
The cut in the quality of printed literature isn't all that surprising. The repetitive nature to what the Witnesses published from the 70s up through the 00s was staggering. I doubt even most devout JWs were reading those magazines regularly, as they had basically already read them hundred of times before.
With an inability to write new and exciting content, given the risks associated with eschatological speculations, the move to video and media is also not surprising.
What I am most curious to know is when will they start including some form of worship service that is not media oriented. At some point that is probably their next big leap, adopting generic worship elements from mainline protestant churches.
My guess, anyway.
