Advertising has evolved significantly over thousands of years from early forms like carving public notices in stone in ancient Egypt to modern digital advertising. Some key developments include the first print ad created in England in 1472, the first electric sign lit in New York's Times Square in 1873, the first celebrity endorsement in 1905, the first political TV ad in 1950, and the launch of internet banner ads in 1994 which led to the rise of pay-per-click search advertising and online video advertising. Modern advertising continues to adapt with new formats like in-text and behavioral targeting ads.
