Web 2.0 has the potential to be a dream come through for businessmen and marketers as it offers an opportunity for free advertising. So what is Web 2.0? The phrase was coined originally by O'Reilly Media and generally refers to the latest generation of websites and web applications that allow increased user participation, rather than the static nature of older websites. We have all seen, and probably participated in, Web 2.0 websites. YouTube, Flickr, FaceBook. Wikipedia and My Space are all Web 2.0 websites, as is every blog you come across on the internet. Because of the participative nature of Web 2.0, you can advertise your product or service free of charge simply by word of mouth. Take this example. Write an informative article describing the history, structure, and services offered by your company and submit it to Wikipedia. If it is genuinely informative and of interest, it will be accepted and you will have a page on one of the most popular websites in the world...for free.
