A software application that allows for the browsing of the World Wide Web.
Everything that is produced for the WWW must take various Web browsers into consideration, and marketing is no exception. Different browsers can have radically different capabilities and limitations.
Some sites try to support almost all existing browsers, while others try to support only the newest and most popular browsers. A middle-ground approach is to have some enhanced features for newer browsers, yet provide graceful degradation for older browsers.
Note: when comparing browser usage statistics, be aware that differences in methodology may skew the results.
