The banner ad, also known as a banner ad, is a classic online advertising format widely used on the internet. With its standard dimensions of 468 x 60 pixels, it pioneered digital advertising, debuting in 1994 on AT&T’s Hotwire website. Over time, other formats emerged, and the traditional banner gradually gave way to the larger banner, megabanner, or leaderboard, which measures 728 x 90 pixels.
