Take that William Shakespeare, Arthur Miller, and Henrik Ibsen.

J.K. Rowling and Jack Thorne's play script for Harry Potter and the Cursed Child is by far the biggest-selling playscript since records began (via The Bookseller); shifting 847, 886 copies worth £8.76 million in its first week alone through Nielsen BookScan's Total Consumer Market.

In a distant second, a Penguin Classic edition of William Shakespeare's Romeo & Juliet, having sold 127,726 copies since 1998; though it should be at least noted the records only encompass individual editions of the play and not the play as a whole. So don't despair too much.

That said, Rowling's book managed to outsell in its first week what the entire Drama Texts, Plays, and Screenplays sub-category did in all of 2015; which itself was supposedly a strong year with 690,577 units sold worth £5.1 million.

It's already the biggest-selling title of the year, achieving the record in a mere seven days; as well as the fourth fastest-selling title of all time. That beats E.L. James' Fifty Shades of Grey by nearly 200,000 copies; though the only books Rowling has failed to surpass is, ironically, her own.

The last three entries into the Harry Potter series - Deathly Hallows, Order of the Phoenix, and Half-Blood Prince - all sold faster than Cursed Child, with Deathly Hallows still holding the record for the biggest-selling single week title, shifting 1.84 million copies.
