This was in the news recently.

A French author tried to get his book published in the traditional way. He had had several books published in the traditional way, but no publisher wanted this particular book of his.

So he published it on Amazon where it did okay.

There was a French national book award and someone submitted his book. And he won.

Now all the booksellers in France are crying about it because they don't carry his book, you can only get it through Amazon. I'm sure that will change at some point.
