Final answer:
A banner ad is a dynamic, graphical ad placed prominently on a webpage, evolved from static images to include animations and interactive elements. Their effectiveness depends on visual appeal and clear messaging, influenced by developments in television and print advertising.
Step-by-step explanation:
A banner ad is a graphical ad, often with animation, placed in a prominent position on a webpage. As the internet has evolved, so too has the sophistication of online advertisements. Initially, web ads were static images, but with advancements in technology, they have become more dynamic, incorporating animation and interactive features. This form of advertising is influenced by earlier developments in television and print media, which placed a strong emphasis on graphic images and recognizable brand logos. The effectiveness of such ads relies on their ability to capture the attention of viewers through visual allure, often leveraging bright colors, eye-catching designs, or animation. Just as with infographics, not all banner ads are created equal; the most successful ones combine aesthetic appeal with clear messaging to effectively communicate the advertiser's intent.
