A Brief History of the Internet

Web 2.0

In the first few years of the World Wide Web, creating and hosting a website required a specific set of knowledge. A person had to know how to set up a web server, get a domain name, create web pages in HTML, and troubleshoot various technical issues.

Starting in the early 2000s, major changes came about in how the Internet was being used. These changes have come to be known as Web 2.0. Here are some key characteristics in Web 2.0.

Universal access to Apps
Value is found in content, not display software
Data can be easily shared
Distribution is bottom up, not top down
Employees and customers can use access and use tools on their own
Informal networking is encouraged since more contributors results in better content
Social tools encourage people to share information

Social networking, the last item in the list, has led to major changes in society. Prior to Web 2.0 major news outlets investigated and reported important news stories of the day.

As discussed, a "killer app" is a use of a device that becomes so essential that large numbers of people will buy the device just to run that application.

With the introduction of the Internet came another killer app – E-mail.

The Internet was originally designed as a way for the Department of Defense to manage projects. However, the invention of electronic mail drove demand for the Internet. While this wasn't what developers had in mind, it turned out that people connecting with people was the killer app for the Internet. As we look back today, we can see this being repeated again and again with new technologies that enable people to connect with each other.
