A great explanation of [|Web 3.0 and the Semantic Web] can be found in the Digital Inspirations blog.


 * Year || Era ||  || Description ||
 * 1982 || The Internet ||  || Though point-to-point connections between mainframes and other computers existed in the 1960's and 1970's, the standardization of the [|Internet Protocol Suite] (TCP/IP) and the concept of a world-wide network of fully interconnected TCP/IP networks is often considered as the birth of the Internet. ||
 * 1991 || The World Wide Web || Web 1.0 || Tim Berners-Lee is considered the inventor of the World Wide Web as he created the coding (hypertext markup language HTML), the tools necessary for different platform computers to send data back and forth (HTTP), the first Web browser, and more. ||
 * late 1990's || The Read Write Web || Web 2.0 || Nothing about the technology infrastructure changed, but software was invented that made it easy to "write" on the Web . . . to publish your writing instantly (blogs, wikis, etc.). Ward Cunningham developed the first wiki in 1994; Wikipedia started in 2001. The term "weblog" was coined by Jorn Barger in 1997, though the idea of publishing one's thoughts and opinions on the Web had been around for a while. The tools for easily posting and editing writing on the Web started in the early 2000's. ||
 * || The Semantic Web || Web 3.0 || Many definitions exist for what this might be, but if semantics are the difference in meanings of words and symbols including interpretations, then the Semantic Web is about personalizing the Web to give it meaning to individual users. Behind the scenes, it's about semantic databases; to the user, it's Google searches that figure out what you might really mean (as opposed to the actual misspelled word you typed) or Amazon making suggestions of products you might be interested in based on your purchasing history and the purchases of others who bought similar products. ||
 * || WebOS || Web 4.0 || You won't need your own personal computer with software installed on your hard drive and an operating system, you'll just go to the Web where software will work through your browser regardless of platform. It really won't be an operating system, it will mean you don't have to have an operating system on your device (no Windows, Mac, Linux, OS wars). A Personal Intelligent Agent, according to Ward Tongen, "finds information for you, acts autonomously, has intelligence and can learn, improving its performance in executing its tasks." Siri on the iPhone is a Personal Intelligent Agent. Web 4.0 is where the Web will be your Personal Intelligent Agent. ||
