Company categories
Rules
Company categories are categorized by industry. To avoid confusion, they are categorized based on how the corresponding article is categorized on Wikipedia.
When transferring the categories from the corresponding Wikipedia article, the following apply:
- Categories must describe the company in a way that relates to the products and services it provides.
- Categories do not contain information about the year or country of establishment. These are not important for the purposes of this wiki.
- Categories that belong to the "Companies by industry" category on Wikipedia belong to the Companies category on this wiki.
