Michelle Obama's book 'Becoming' has longest run on Amazon's bestseller list since 'Fifty Shades'

Former first lady Michelle Obama's memoir "Becoming" is now one of the top-selling books of the decade.

The title has maintained its status as Amazon's best-selling book for nine weeks, the longest run at number one any book has had since the massively popular "Fifty Shades of Grey" came out in 2012.

Obama's book, which was officially released on November 13, 2018, skyrocketed to No. 1 on Amazon the Friday before its publication date.

According to the online retail giant, "Becoming" momentarily lost the top spot on day 47 of its impressive streak but returned a few hours later and has held fast to its status ever since.

Only seven other titles have enjoyed longer streaks at No. 1. since the company began compiling its book sales this way in 1995, according to CNN Business.

Four of those were from J.K. Rowling's iconic Harry Potter series, including, "Harry Potter and the Goblet of Fire" in 2000, "Harry Potter and the Order of the Phoenix" in 2003, "Harry Potter and the Half-Blood Prince" in 2005 and "Harry Potter and the Deathly Hallows" in 2007.

The three remaining titles were Dan Brown's "The Da Vinci Code" in 2003; Eckhart Tolle's "A New Earth: Awakening to Your Life's Purpose," which was part of Oprah's Book Club, and "Fifty Shades of Grey" in 2012.

"Becoming" also notably holds the all-time record for weeks spent in the top spot on Amazon for a memoir written by a political or public figure.
