A web browser is the software program you use to retrieve and view webpages and other content on the Internet. The most popular browsers today are Google's Chrome, Mozilla's Firefox, Microsoft's Internet Explorer, and Apple's Safari. These programs are free to download, and users may have more than one browser on their computer or other device. In general, third-party advertising companies associate interest categories or audience segments with a particular browser -- not with a person -- to serve ads.
