Social Media has changed the way people interact on the web. Instead of just reading content on the web, people are able to change what they want the webpage to look like. A good example of this is Weebly, Facebook, Tumblr, and Blogger. All these websites use server side scripting to allow the content to change dynamically with the help of a Web 2.0 site.
Differences between Web 1.0 and Web 2.0
NOTE: Web 2.0 isn't an incremented software version, it just provides a way of describing the way people make and utilize websites. 
|Ability||Web 1.0||Web 2.0|
|CSS||✘ Tables, inline HTML codes (e.g. background)||✔|
|Forms||✘ (mailto only)||✔|
|e-commerce||✘ (view only - like a brochure)||✔|
Before Zuckerberg was in Harvard and as a kid, he created games from the pictures his friends drew and also made a network messaging program called Zucknet that his father used in a dentistry to chat to his receptionist. Facebook has both messaging and gaming that allow many people to communicate and be entertained. Amazingly, Zuckerberg started programming at the age of 12 from his interest with computers that a privately hired computer tutor had difficulty keeping up. AOL and Microsoft asked Zuckerberg about buying a basic program called Synapse and to also hire him before graduation, but he rejected the offer. 
Zuckerberg also made a voting system to rate people based on attractiveness in Harvard but it got stopped by school administration, as seen on the popular movie The Social Network.
Facebook was made in 2004 whilst Zuckerberg was still in Harvard. It was originally called TheFacebook and the web address; thefacebook.com. He decided to make Facebook with his friends after dropping out of a project called Harvard Connection. The creators of Harvard Connection then filed lawsuits towards Zuckerberg after they realised what he was up to. However, Zuckerberg's idea was different because Zuckerberg didn't make a dating website. Zuckerberg also opened up facebook to the public instead of limiting it to universities after he realised how popular it could be.
Facebook is now the most popular social networking platform out there and allows around 1.3 billion people to communicate all at the same time to whoever they want. Facebook allows us to share information and talk to others quicker. By allowing us to share our thoughts, opinions and inspirations, we allow our friends to be able to connect with us like we've never done before. We can the also share the love we have for our inspirations like being able to connect in groups and feel as part of a community. There are many communities too who like most of the things you do so you're not just limited to your local neighbourhood.
Not only can we communicate with others, we can play games alongside our friends whether its in real time or just helping your friends garden grow whilst their away. We can see our friends through webcam sessions instead of just talking too and we can initiate group chats with our friends so that we can all chat at once if we need to. This can be useful for birthday parties, university friends, family, old friends and so on. We can send our friends files and pictures which can be from a computer manual to a picture of your favourite cat.
We're not just limited to the Facebook website either. We can go onto many websites and be able to share content such as a BBC link to a favourite TV programme such as Doctor Who or signing in to a website and being able to use their services whilst telling friends what you have done with that service to promote them and to allow your friends to experience something that they themselves haven't seen, heard or used before. That means that local pubs in your area and public services like BBC can get feedback and upgrade their quality of service to the public and in turn, get more profit from more customers recommending a service.
New services in Facebook
Geolocation is a new technology that has recently been included in Facebook that allows users to include where they are. This means that businesses can have locations and can allow users to say that they've been here as proof and will allow the review to be authentic. We also have a new feature for our posts that allow us to say what emotion we feel or say what we're doing. This in turn removes the need for emoticons that can sometimes get in the way of the original message and misunderstanding.
Facebook has been growing ever since it existed in the simpliest form where Facebook at the end of 2004 had 1 million users. It is still growing everyday and has around 1.23 billion users that are frequently active . Other social media sites are growing too but they are limited in what they can achieve. For example, YouTube and Vine can only share video, Twitter can only show follower posts, Soundcloud can only share music. It's fair to say that they cannot all copy Facebook and try and leave Facebook users the way MySpace users left. However, being able to share a variety of information such as videos, pictures and websites allow flexibility. Facebook is also so popular that the main reason people are still on it or join it, is because they want to be able to chat to people that they might not be able to (easily) otherwise.
