Banner Ads have always been a source of controversy online. The precursor of pop-up ads, they have been around for a long time, but not everyone has gotten used to them.
With most banner ads, the websites that display them and the company that places them are well-meant. They are not different from ads in a magazine or on TV. The controversy arises in the high-tech exchanges that use search results, cookies and other personal web stats to give you a personalized ad. While a television network must assume that since you are watching a certain program, you probably fall under a certain demographic, banner ads can have you precisely narrowed down. This is seen by many as a serious invasion of privacy.
There has been further scrutiny with spyware programs that are hidden in downloaded files to track internet usage and help banner and pop-up ad selection. Other programs, such as Gator, advertise themselves as a programs for one purpose – in Gator’s case an on-line shopping assistant – but allegedly have banner and pop-up ad data mining as their main objective.
