Web 2.0
Since 2004 the term “Web 2.0” has been used to describe the social web. This new title wasn’t used to describe a change in specific web technology, but instead a change in the way websites were created and used. During the rise of Web 2.0 social media became an essential tool for every single individual with most web users beginning to interact and collaborate in virtual communities. This gave rise to the popularity of websites that emphasized user generated content through social media like Facebook and Twitter or crowd sourcing websites such as Wikipedia and Trip Advisory. Now, because of this user engagement, the web has become more open, more connected and more intelligent, leading us to our current state.
