Please give a brief history of browsers and their providers, including who dominates the market, who was an early forerunner and went out of business, and who are the recent strongest browsers. Why do you think certain browsers are more popular? How did you choose the browser you currently use and what played a part in your decision?
What will be an ideal response?
The dominant Web browser for the past two decades has been Microsoft's Internet Explorer. Internet Explorer's early forerunners and innovative competitors, National Supercomputing Center's freeware browser Mosaic and Netscape Navigator, have all but evaporated from common use. Fortunately, a recent renaissance in browser development has produced some challenging mainstream competitors to Internet Explorer, including Mozilla's Firefox, Apple's Safari, and Google's Chrome.
Reasons for the popularity of certain browsers include (student answers will vary):
Distribution (Microsoft Internet Explorer is provided with new PCs)
Cutting edge development and innovation
Lively, supportive online communities
Availability of source code
Ability to customize user experience
Ability to use the browser on both home computers and mobile devices
