The cookies caught on around Whitman, and so did the ingredient. Sales of the Nestlé bar rose, and Carolyn Wyman, who wrote a book about the cookie, says the company sent a salesman out to find Wakefield.
Beginning in 1939 the Wakefields signed a series of agreements handing Nestlé's predecessor, Lamont, Corliss and Company, exclusive rights to the Toll House name for chocolate and food products. By 1948 the arrangement had gone far enough that Lamont, Corliss had to give the Wakefields permission to put Toll House on a cookie.
What Wakefield got in return is not on the record. Wyman found that nobody involved, Wakefield's daughter included, would say what the agreement contained. The New York Times reports the popular version, one dollar and a lifetime of free chocolate, with a supposedly in front of it.
