Companies want in the browser market as they can then collect usage data. This is why companies like Google develop and maintain browsers at no charge to the consumer. As of 2017, according to the federal government's Digital Analytics Program (DAP), Chrome currently dominates the browser market with over 44% market share. This is small compared to what Microsoft’s Internet Exploder’s 90% market share which is now down to 15% and 3% for their new “Edge” browser. Other browsers exist including Tor to browse the deep/dark web. As previously discussed, the browser sends requests through the Hypertext Transfer Protocol. The browser requests a file from the server and then converts the file it receives into something visual. When we look at a website we often do not think about what is behind the scenes. If we ever were to view the source of the website we would see the markup used to create the page. This markup is called HyperText Markup Language or HTML. There are other files referenced by the HTML file including images, fonts, colors and interactions which are pulled together by the browser to form what we see.
