I think its now easy see the long standing and continuous operation of the Watchtower Corporation and its commercialized corruption as a religious publishing house.
The core centralized intent was to increase the circulation and distribution of the WTS's own publications. They exploited the basic belief in the bible as holy spiritual writings and used the end is near proclamation all throughout the 20th century and even back toward the end of the 19th century.
These leaders also devised special engaging public talks at assemblies and local kingdom halls which were also devised to support those specific core doctrines of Christ's return and a imposing question of who's worthy of being saved or not at the soon to come day of judgment Armageddon.
The WTS. also devised strategies to train people at Kingdom Halls in how to present these self devised doctrines to the public in the door to door service work, identifying it as serving Jehovah as preaching a true correct Gospel of Christ's new Kingdom to come.
People were blindsided to the fact that these doctrines were not accurate or true bible interpretations but ones made and created intentionally to proliferate literature.
They were in essence falsely made up doctrines which didn't really have any biblical support.
In very true sense the WTS was and still are commercialized false prophets.
