This is the new link.
Though I've discussed it before it seems when I post about it again that new readers are immediately shocked and surprised. If you're an author and you want to understand more about why things are the way they are then you need to go to the link above and read it thoroughly.
For your viewing pleasure I will only quote some excerpts:
"The 1920s saw the founding of such important publishing houses as Simon and Schuster, Random House, Alfred A. Knopf, and Viking Press. Although Random House would grow to be the largest and most successful publisher in the country, and would hold that position into the twenty-first century, Simon and Schuster introduced some important industry innovations with long-term consequences."
