New York Times reported in 2005 that income from the CTW's international co-productions of the series was $96 million. By 2008, the Sesame Street Muppets accounted for between $15 million and $17 million per year in licensing and merchandising fees, divided between the Workshop and Henson Associates. The Workshop began pursuing funding from corporate sponsors in 1998; consumer advocate Ralph Nader urged parents to protest the move by boycotting the show. In 2018, the Workshop made a deal with Apple to develop original content, including live-action, puppet, and animated series, for Apple's streaming service. In 2019, Parade Magazine reported that the organization had received two $100 million grants from the MacArthur Foundation and from the LEGO Foundation; the funds were used to undertake "the largest early childhood intervention in the history of humanitarian response to help refugee children and families". Publishing In 1970, the CTW established a department managing the development of "nonbroadcast" materials based upon Sesame Street. The Workshop decided that all materials its licensing program created would "underscore and amplify" the series' curriculum. Coloring books, for example, were prohibited because the Workshop felt they would restrict children's imaginations. The CTW published Sesame Street Magazine in 1970, which incorporated the show's curriculum goals in a magazine format. As with the series, research was performed for the magazine, initially by CTW's research department for a year and a half, and then by the Magazine Research Group in 1975. Working with Random House editor Jason Epstein, the CTW hired Christopher Cerf to manage Sesame Streets book publishing program. During the division's first year, Cerf earned $900,000 for the CTW. He quit to become more involved with writing and composing music for the series, and was replaced eventually by Bill Whaley. Ann Kearns, vice president of licensing for the CTW in 2000, stated that Whaley was responsible for expanding the licensing to other products, and for creating a licensing model used by other children's series. As of 2019, the Workshop had published over 6,500 book titles. and as researcher Renee Cherow-O'Leary stated in 2001, "the print materials produced by CTW have been an enduring part of the legacy of Sesame Street". In one of these books, for example, the death of the Sesame Street character Mr. Hooper was featured in a book entitled I'll Miss You, Mr. Hooper, published soon after the series featured it in 1983.
