What is show archiving for?

If you have finished a show, you can archive it: it will be set aside in a "Archived and finished shows" section on your My shows page and will no longer be mixed in with the other shows you are currently watching.

This can also be used to archive an unfinished show so that it no longer appears in your schedule if you decide to stop watching it. In that case, it will be placed in the "Archived shows" section.

Finally, when you add a show and archive it without starting it, it will be placed in the "Archived and not started shows" section.
