Mr. Men is a British series of children's books written and illustrated by English author Roger Hargreaves which began publication in August 1971.

Each book in the original Mr. Men and Little Miss series introduced a different title character and their single dominant personality trait to convey a simple moral lesson.

[2] The books' simple stories, with brightly coloured, boldly drawn illustrations, have sold over 100 million copies worldwide across 28 countries.

According to John Malam, who wrote Roger Hargreaves' entry in the Oxford Dictionary of National Biography, the inspiration for his initial creations came while doodling at work.

Malam told Amelia Tait of the New Statesman in 2021 of the anecdote about his son's query: "It became too good to dispute and no doubt helped in the early marketing campaigns.

A competition was held in the British Sunday Times newspaper for children to submit their own Mr. Men character for inclusion in a limited edition celebrating the 30th anniversary of the series.

Her creation led to a book featuring her character being published; it was sold only in W H Smith branches, with a portion of the proceeds going to a charity, supporting children with leukemia.

In April 2004, Hargreaves' widow Christine sold the rights to the Mr. Men and Little Miss characters to UK entertainment group Chorion for £28 million.

[11] On 6 October 2021, it was announced that a brand new Mr. Men Little Miss television series would be created by Endeavor Content.

[14] Instead of being in a reduced font size, it curves down at the end where the name of the titular Mr. Men character is too long to fit on the cover horizontally.

The stories are set in a fictional universe called "Misterland", which is inhabited by the Mr. Men and Little Misses themselves, as well as some ordinary human characters such as shopkeepers, doctors and postmen.

Less than a year later, reruns on both Little Miss and Mr. Men were moved to BBC2 beginning on 27 January 1988 until its last airing on 22 December 1988.

This was the first Mr. Men based series to air in the United States, getting 2 VHS releases from Warner Home Video with an American redub in 1986.

Another series, Mr. Men and Little Miss, was produced by Marina Productions in 1995 and originally aired on British and Irish television from 1995 to 1997; these stories had in it Geoffrey Palmer, Gordon Peters as the narrator, and Jill Shilling and were aired on Nick Jr. and Channel 5's Milkshake!

By the beginning of 2007, Chorion had its series of books licensed to Renegade Animation to produce The Mr. Men Show which debuted on the Cartoon Network in North America and on Channel 5's Milkshake!

The series was written and produced by Eryk Casemiro and Kate Boutilier and directed by Mark Risley.

The creative team was a combined effort of personnel from Nickelodeon's Rugrats, The Wild Thornberrys, and As Told by Ginger.

[5] All of the opening and closing parts are narrated by Joey D'Auria (credited as Joseph J. Terry) in the US and Simon Callow in the UK.
