Football Kit Design Timeline
1979-80
Liverpool becomes the first Football League team to wear sponsored shirts. They bear the name of Japanese electronics company Hitachi, and would continue to do so until the end of the 1981-82 season.
Perugia becomes the first Italian Serie A club to wear sponsored shirts. A small version of the logo for Ponte (a maker of pasta products) appeared below the club badge and, technically, was not legal at this time. As the Italian football authorities only allowed a manufacturer logo to be shown, the club's then chairman, Franco D'Attoma, circumvented the rules by establishing a sportswear company called Ponte Sportswear.
