The worldwide network of Scientology organizations consists of numerous entities and corporations, located in the United States as well as in other countries. All these organizations are interrelated and connected through an internal hierarchy system, which is called the "Command Channels of Scientology".
At the top of the "Command Channels" are management corporations, such as the Religious Technology Center, the Church of Spiritual Technology, or the Church of Scientology International, who own and license the Scientology trademarks and service marks to other entities and corporations within the internal hierarchy system of the network.
Within the sphere of the upper Scientology management exist also several corporations with specific functions with regards to publication, distribution, administration, and finances. Examples are the Scientology-owned publishing house Bridge Publications or the World Institute of Scientology Enterprises, which promotes and sells Scientology services to businesses and entrepreneurs.
