This is just crazy.

There's a lot of conglomeration in the publishing industry, too. It's utterly mind-boggling.

Vintage International, for instance, is an imprint of Vintage Books which is a subsidiary of Alfred A. Knopf Inc., which was acquired by Random House in 1960. (Alfred A. Knopf, Jr. had left the company and founded Antheneum Books in 1959. Antheneum was itself acquired by Simon & Schuster ever since that company's acquisition of Macmillan in 1994.) Random House was later acquired by Bertelsmann.

Meanwhile, the Knopf Publishing Group merged with Doubleday, forming the Knopf Doubleday Publishing Group. Random House, which is the parent company of those two, has been owned by a joint venture between German Bertelsmann and British Pearson since the 2013 when Penguin Group and Random House merged.

My head is spinning.
