The group performed an estimated two hundred concerts a year, with an extravagant worldwide concert tour that summer, called "The Magic Summer Tour", sponsored by Coke. The tour ultimately grossed $74 million ($133 million, adjusted for inflation), making the group the top-grossing touring act in the country at the time and one of highest-grossing concert tours of the decade. The tour had an overall attendance of 3.2 million people. Their 1990 pay-per-view special broke cable-TV history at the time. During this time, the group became heavily merchandised. NKOTB-licensed merchandise included lunch boxes, buttons, T-shirts, comic books, dolls, trading cards and even a Saturday morning cartoon in their likeness, which was developed by the writing and development team from Pangea Corporation and animated by DIC Entertainment. In 1991, sales for the group's merchandise were estimated at US$400 million.
