Pop-ups were invented in the 1990s by Ethan Zuckerman and first appeared on Tripod.com pages, allowing automatic small windows to open and advertise products on websites. The first sponsorship video aired in 1946 when commercial TV licenses were granted, and Coronation Street has been sponsored over the years by Cadbury's, Harvey's, and Compare the Market. Existing fashion companies like M&CO and Isme.com sponsor television programs like The National Weather and Loose Women through advertisements.
