Pearson Education is a British-owned education publishing and assessment service to schools and corporations, as well for students directly. Pearson owns educational media brands including Addison–Wesley, Peachpit, Prentice Hall, eCollege, Longman, Scott Foresman, and others. Pearson is part of Pearson plc, which formerly owned the Financial Times. It claims to have been formed in 1840, with the current incarnation of the company created when Pearson plc purchased the education division of Simon & Schuster (including Prentice Hall and Allyn & Bacon) from Viacom and merged it with its own education division, Addison-Wesley Longman, to form Pearson Education. Pearson Education was rebranded to Pearson in 2011 and split into an International and a North American division. Although Pearson generates approximately 60 percent of its sales in North America, it operates in more than 70 countries. Pearson International is headquartered in London, and maintains offices across Europe, Asia and South America. Its online chat support is based in the Philippines. Pearson North America is headquartered at 330 Hudson in New York City, New York. It previously was located in Upper Saddle River, New Jersey. Pearson International is headquartered at 80 Strand, London, UK. Pearson Italia SpA, also known as Pearson Paravia Bruno Mondadori, was created through the purchase of PBM Editori, which was, in turn, a merge of Paravia (based in Turin) and Bruno Mondadori (based in Milan). Imprints Pearson has a number of publishing imprints: Logo Pearson's logo is the unconventional symbol known as the interrobang (‽), a combination of a question mark and an exclamation point, meant to convey "the excitement and fun of learning." Partnerships Pearson has partnered with five other higher-education publishers to create CourseSmart, a company developed to sell college textbooks in eTextbook format on a common platform. In 2010, Pearson agreed to a five-year, $32 million, contract with the New York State Department of Education to design tests for students attending grades 4 through 8. GreyCampus partnered with Pearson for higher-education teaching-learning solutions under the Learningware brand. Que Publishing, a publishing imprint of Pearson-based out of Seattle, partnered with AARP to develop and add to a series of technology books for seniors. The series, which includes My iPad For Seniors, and My Social Media for Seniors, are large-print and colourful. Errors in tests In the spring of 2012, tests that Pearson designed for the NYSED were found to contain over 30 errors, which caused controversy. One
