No, really, you did not invent the genre. Genres are marketing labels invented by marketers for readers to help them group similar books and sell to readers by association. It’s the “You might also like…” function of book selling from pre-Amazon days.

Writers and authors being aware of their genre is the same as being aware of their audience. It’s a simple way to say “I know my audience”. Genres and audiences are tools of selling, not tools of writing.

You did not invent a genre any more than your editor invented a genre or your agent invented a genre.

And that goes for you “Teh genre is dying!!!” people too.
