Michelle ObamaMichelle LeVaughn Robinson ObamaJill Biden, Kate Middleton to meet this week Jill Biden to focus on military families on foreign trip Book claims Trump believed Democrats would replace Biden with Hillary Clinton or Michelle Obama in 2020 election MORE’s publisher says the former first lady’s “Becoming” could be the “most successful memoir in history.”

The book has sold nearly 10 million copes around the world since it hit shelves in November, according to Penguin Random House.


“I’m not aware, in my personal experience with Penguin Random House, that we ever sold 10 million units of a memoir,” chief executive Markus Dohle told The Wall Street Journal on Tuesday.

“We believe this could be the most successful memoir in history,” said Thomas Rabe, a chief executive for the publisher’s co-owner, Bertelsmann.

A Penguin Random House spokeswoman confirmed the numbers, telling ITK on Tuesday that, in the United States and Canada alone, "Becoming" has "sold more than 6.2 million units across print, digital, and audio formats since its publication."

Obama, 55, released her memoir last year with a media blitz and an international, star-studded book tour, with stops in stadiums and arenas around the world.  

“Becoming” was declared the best-selling hardcover book of 2018 shortly after it was published. Earlier this year, Amazon announced Obama's memoir had the longest run as its best-selling book since 2012's "Fifty Shades of Grey."
