web surfers regard these advertisements as highly annoying because they distract from a web page's actual content or waste bandwidth. (Of course, the purpose of the banner ad is to attract attention and many advertisers try to get attention to the advert by making them annoying. Without attracting attention it would provide no revenue for the advertiser or for the content provider.) Newer web browsers often include options to disable pop-ups or block images from selected websites. Another way of avoiding banners is to use a proxy server that blocks them, such as Privoxy.
