A banner ad is a graphical internet advertising tool in which visitors click on the graphic to be taken to another website.
Early banner ads typically ran across the top of a web page. They were first created by hotwired.com (website of Wired magazine), which was launched in October of 1994.
Banner ads now refer to ads of varying sizes and positions.
