- John Cadbury began selling tea, coffee, and drinking chocolate in 1824 in Birmingham, England, which he produced himself. Over time, he expanded into cocoa and chocolate production with his brother Benjamin under the company Cadbury Brothers. - In 2008, worms were found in some Cadbury Dairy Milk chocolate bars in India, causing sales to plummet and damaging the company's credibility. Cadbury developed messages that the issue was due to storage problems and its chocolate was still safe to eat. - Cadbury launched "Project Vishwas" involving quality control checks, engaged Amitabh Bachchan as a brand ambassador, and revamped packaging to restore consumer confidence and sales.
