The series reached a record high for viewing figures in October, with 555,600 tuning in to CBeebies.
As the figures soar, master toy licensee, Vivid Imaginations is developing an extensive new range of product for 2012.
Neil Bandtock, MD, commented: "Rosie sales are showing double digit growth week-on-week and we have strong plans in place across nationwide distribution to support the brand moving into 2012."
The toy range includes plush, plastic figurines, play-sets, puzzles and role-play toys.
MD of V&S Entertainment, Vickie Corner, commented: "We're thrilled with the ongoing success of Rosie and the fact the audience share continues to grow is great testament to the high quality production values and core values of the series."
The toy range is supported by a publishing plan by Egmont UK which launched the first phase of books in October with its 10 Minute Tale title, a colouring activity book and sticker book. New titles for 2012 include Funny Faces Sticker Book, Magnet Book and Story Collection.
David Riley, managing director, Egmont Publishing Group said: “Everything’s Rosie is a fresh and contemporary pre-school show with great storytelling which translates effortlessly into print.
"We are delighted by the response at retail and have high expectations for the brand going forward. We Love Rosie.”
