On January 11, 1964, US Surgeon General Luther Terry released a report that concluded cigarette smoking caused a large rise in deaths and was the chief cause of the epidemic of lung cancer in the twentieth century. An advisory committee of ten experts reviewed more than 7,000 scientific articles and estimated that smokers had a nine to ten times higher risk of lung cancer than non-smokers, with heavy smokers at least twenty times higher. Terry chose a Saturday release to limit stock market effects and reach Sunday papers. Congress later required health warnings on cigarette packs in 1965 and banned television and radio cigarette advertising from 1970.

Hampi is a UNESCO World Heritage Site in Karnataka, India, with more than 1,600 surviving remains spread over 4,100 hectares. It was the capital of the Vijayanagara Empire from 1336 to 1565. Travellers from Persia and Portugal described it as a prosperous, wealthy and grand city with temples, markets and farms along the Tungabhadra River. By 1500 it was estimated to be the world's second-largest city after Beijing, and probably India's richest at the time. In 1565 a coalition of Muslim sultanates defeated the Vijayanagara Empire, its capital was conquered and destroyed, and the city was left in ruins. Hampi remains a religious centre, with the active Virupaksha Temple at its heart.
