In 2011, Sanrio, the Japanese design company best known as the creators of Hello Kitty, announced that they had reached an agreement to acquire the rights to the Mr. Men and Little Miss characters from Chorion after the company was forced into administration. This marked the first time that Sanrio had licensed a third-party character since owning the rights to Osamu Tezuka's Unico character in the late 1970s and early 1980s, which was returned to Tezuka Productions after Tezuka's death in 1989. Sanrio had also acquired the license to produce Peanuts merchandise for the Japanese market. In 2016, four new characters were launched to celebrate the series' 45th anniversary, Mr. Marvellous, Mr. Adventurer, Little Miss Fabulous and Little Miss Sparkle. In addition, Adam Hargreaves has created several commercial characters such as Mr. Glug for Evian water and Mr. First for money transfer company World First. In 2017, Adam Hargreaves launched a new series of books featuring characters from the BBC science fiction series, Doctor Who, with each book focusing on a different incarnation of the show's titular character.
