Quite succesful in the Netherlands.

In 2003, after discovering that the majority of chocolate produced at the time had links to human exploitation, Dutch television producer and journalist Teun van de Keuken began producing programs about the horrors of the commercial cocoa industry on his show Keuringsdienst van Waarde. Furthermore, he submitted a request to be prosecuted for knowingly purchasing an illegally manufactured product, which prosecutors declined to do.

After three years of unsuccessful attempts to change the industry through investigative efforts, Van de Keuken decided to start producing chocolate bars himself. The brand was called "Tony's Chocolonely" with "Tony" (= Teun) and "Chocolonely" in reference to Teun van de Keuken feeling as if he was the only person in the industry who was interested in eradicating slavery. Van de Keuken sold 20,000 bars in two days.
