Content in specific webpages, coded in HyperText Markup Language (html), is directly accessible in the Web. This problem was solved by significant advances in the search engine, specifically with the advent of Google in 1998 and their backlink 'voting' algorithm for ranking page relevance. Up through the late 1990s, browsing the web was frequently frustrating when trying to find specific content. But even the Web was in want of an engaging User Interface, and this was provided by the web browser, where images could be displayed along with text and hyperlinks. The World Wide Web was a significant advance in accessing information on the Internet, by implementing the HyperText Transfer Protocol (http). It is said that email was the first extremely popular application of the Internet. The Internet is the formation consisting of a 'network of networks', enabled globally through a standard Internet Protocol (IP). These two columns can be thought of as the 'first wave' and the 'second wave' in construction toward the internet.Ī network is formed when multiple computers are linked together. For example, while computers were around since the 1940s, it was not until the advent of inexpensive personal computers in the mid-1970s that the Internet revolution could be enabled. Listed on the right side are the more refined advances that helped to enable major breakthroughs. Listed on the left side are the highlighted rudimentary advances.

Significant milestones are highlighted in columns on the left and right, showing key contributions made by some of the instrumental people involved in inventing and developing the technology.
