Initially, the sandwich was made with a plain bun; however, that changed when the company switched to a sesame-seeded bun around 1970.[9] In 1985, the weight of the Whopper was increased to 4.2 oz (120 g), while the bun was replaced by a Kaiser roll.[10] This was part of a program to improve the product and featured a US$30 million (approx US$66 million in 2014)[4] advertising campaign featuring various celebrities such as Mr. T and Loretta Swit.[11] The goal of the program was to help differentiate the company and its products from those of its competitors.[12] The Whopper reverted to its previous size in 1987 when a new management team took over the company and reverted many of the changes initiated prior to 1985.[13] In 1994, the Whopper sandwich's Kaiser roll reverted to a sesame seed bun, eliminating the last trace of the sandwich's 1985 reconfiguration.
