Your own magazine, newsletter, annual report, etc. Why choose printing while you can also use the internet? One can reach a much bigger audiance and it's more flexible. You can adjust it any moment. A CMS is actually a publishing tool. It is mostly used for websites but certainly with the modern 'page builder' plugins you can build a complete magazine.
It is interactive, it is easier to search and you can reach more people with it. If you do not want everyone to see it, you can hide it behind a login page.
Off course, the publication is 'responsive' so that it can also be read on tablet on smartphone.
