ROJW was officially formed in 2000, paperwork was probably prepared and started to go through the NY Secretary of State office in 1999. Prior to this, bethelietes and other special full time servants still took a vow of poverty and obedience just under a different Corporation. In 2000 there was setup 7 US corporations to handle matters in the US.
WTBTSPA- it is the parent corporation and publishes the material.
WTBTS-NY- they oversee operations such as printing the material.
CCJW- they are the corporation's that service department has control over, elders and co duties fall under this
Worldwide Order of Special Full-time Servants of Jehovah's Witnesses- is the corporation that oversees bethelietes and COs, construction volunteers and US BIFS. They oversee the actual person not the work.
Kingdom Support Services- oversaw the work at bethel, RBCs, transportation of literature and a few other stuff.
WTBTS-FL- they owned a orange grove at one time, but I think they got rid of it because ur became cheaper just to buy oranges.
WTBT-NJ- I am not sure what they do, I just know it exists. I believe all it does now is handle Stanley theater.
There is a corporation that handles the cemetery at wallkhill, but I forget it's name.
Recently there was added a new corporation to handle the US LDC operation
