I would say Jehovah's Witnesses are in a religion that was created around a publishing company for the purpose of obtaining religious tax exemption. Watchtower was, is, and shall be the controlling entity of the religion. As the US Federal government started to crackdown on religion-for-profit, Watchtower changed to ensure it maintained its tax exemption.
We saw this when HQ stopped using Watchtower letterhead and invented the "Christian Congregation of Jehovah's Witnesses." In addition, it was common place, even by some JWs today, to invoke the name of "The Society"(short for Watchtower Bible and Tract Society) as an authority on a matter (e.g. "The Society says <insert belief>).
Looking back, JWs were nothing but door-to-door salesmen selling Watchtower publications. That is why members are referred to as "publishers." That's what a publisher does - sells books, magazines, and other printed materials. JWs purchased the books from Watchtower, then sell the books to non-JWs in their ministry, and funds from both sales are then "donated" to Watchtower. Labor to manufacture said publications is donated. It was quite the scam until the America television evangelists started getting fed time for tax evasion.
The new Watchtower business model is to have JWs purchase loans to build Kingdom Halls, which are later sold by the same JWs who bought the loan, and then the JWs donate the money back to Watchtower. Its the same scam, but with real estate rather than books.
