So I created a very interesting name for what we do and even created a name for the industry we work in. Now I want to write an article on Wikipedia about this new (created by me) industry. Does anyone know if I can mention our company in this article? Is it allowed? I would like to say that we invented such name for this new industry and say something like "One of the most successful company working in this new ABC industry is... (our company`s name)???? I spent good 3 hours on Wiki site and didn`t find anything that helps. Should I just write the article or should I check some other resources before?
