Web 1.0, Web 2.0, and Social Media

This picture shows the people's interest on Web 1.0, Web 2.0, and social media from 2004 to 2016 (predicted). We could find that Web 2.0 and social media interest people much more than Web 1.0 does. Also, since 2006 and 2009, Web 2.0 and social media respectively have increased greatly. Moreover, from 2009, Web 2.0 seems to decrease and till 2016 it is predicted to interest people at a same low level as Web 1.0.

Next, let us see history of some famous companies (from Wikipedia).

Facebook:
Launched on February 4, 2004;
Be opened to everyone at least 13 years old on September 26, 2006;
Increased steadily after 2009;
Have 500 million users in July 2010, which makes it to be the largest online social network in the world at the time.

Twitter:
Launched in July 2006;
Have more than 100 million users in 2012.

LinkedIn:
Launched on May 5, 2003;
Have 20 million members in 2006;
Have more than 364 million acquired users in 2015.

Yelp:
Launched ( as service to provide unsolicited online reviews) in late 2005.

YouTube:
Created in February 2005;
Have a market share of around 43% and more than 14 billion views of videos in May 2010.

Therefore, I have the following findings:

1. Around 2006, people show the highest interest in Web 2.0, which emphasize on user-generated content and interaction between users.
2. With the high interest in Web 2.0, companies that apply the two main features of Web 2.0 are created by people successively, for example, Facebook, YouTube, and Yelp.
3. Although people's interest in Web 2.0 began to decrease since 2008, another term, social media, has given rise to people's interest. And thus services that aim to maintain and expand people's social networking have increased rapidly since then. Till now, Facebook, Twitter, and LinkedIn, for example, are still hot topics.
