Full Banner (468x60) - The original. On October 27, 1994, HotWired.com ran the world's first banner ad - a 468x60 from AT&T that asked "Have you ever clicked your mouse right HERE?" with an arrow pointing at itself. 44% of people who saw it clicked. The dimensions were chosen to fit the most common monitor resolution of the day (640x480) with room for page margins. The Internet Advertising Bureau (IAB) codified 468x60 as the standard "Full Banner" in 1996, and for the next decade it was THE shape of internet advertising. Every GeoCities page, every web ring, every free email service - plastered with these glorious rectangles.
