Web 2.0

Beginning in 2002, new ideas for sharing and exchanging content ad hoc, such as Weblogs and RSS, rapidly gained acceptance on the Web. This new model for information exchange, primarily featuring DIY user-edited and generated websites, was coined Web 2.0.
The Web 2.0 boom saw many new service-oriented startups catering to a new, democratized Web. Some believe it will be followed by the full realization of a Semantic Web.
Tim Berners-Lee originally expressed the vision of the Semantic Web as follows:[7]
I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The ‘intelligent agents’ people have touted for ages will finally materialize.
– Tim Berners-Lee, 1999
Predictably, as the World Wide Web became easier to query, attained a higher degree of usability, and shed its esoteric reputation, it gained a sense of organization and unsophistication which opened the floodgates and ushered in a rapid period of popularization. New sites such as Wikipedia and its sister projects proved revolutionary in executing the User edited content concept. In 2005, 3 ex-PayPal employees formed a video viewing website called YouTube. Only a year later, YouTube was proven the most quickly popularized website in history, and even started a new concept of user-submitted content in major events, as in the CNN-YouTube Presidential Debates.
The popularity of YouTube and similar services, combined with the increasing availability and affordability of high-speed connections has made video content far more common on all kinds of website. Many video-content hosting and creation sites provide an easy means for their videos to be embedded on third party websites without payment or permission.
This combination of more user-created or edited content, and easy means of sharing content, such as via RSS widgets and video embedding, has led to many sites with a typical "Web 2.0" feel. They have articles with embedded video, user-submitted comments below the article, and RSS boxes to the side, listing some of the latest articles from other sites.
Continued extension of the World Wide Web has focused on connecting devices to the Internet, coined Intelligent Device Management. As Internet connectivity becomes ubiquitous, manufacturers have started to leverage the expanded computing power of their devices to enhance their usability and capability. Through Internet connectivity, manufacturers are now able to interact with the devices they have sold and shipped to their customers, and customers are able to interact with the manufacturer (and other providers) to access new content.
