Social Networks

Social networks had change our lives. They did changed the way we communicate, the way of doing things, etc. Nowadays people usually use social networks like Facebook, Instagram, Snapchat, Twitter...
Internet is another world, there you can be a person absolutely different from real life. There you can post pictures, send messages to friends that you not usually see, post opinions of a concretly theme, etc, and a lot of things more. 

Facebook was created by Mark Zuckerberg in 2004, this social network did improve a lot, there you can add friends simply searching his name in the browser, you can post pictures and also people can react to your picture giving you a like or leaving a comment. In Facebook you can meet a lot of people but this can be dangerous if you don't take care. There are a lot of people what commit crime through Facebook.
In my opinion, Facebook had been a good social network in the past because I used to be all time connected on it, also it was the first social network I'd have. Currently I use another social network named Instagram.

Now, Instagram is one of the most popular social network. It was created by Kevin Systrom in 2010. It changed a lot, there you can post pictures and videos. In Instagram, you can tag people in a picture, also you can give like and comment if you like a photo like Facebook. The thing what makes popular Instagram was the hashtags. In Instagram you can follow people that you want to see his pictures.

Finally another sovial network that is increasing a lot is Snapchat. This social network is only avalible for smartphones. It consist in post photos and videos that people only could see it during one day. When a day passed, the picture or video is automatically deleted.

This are only an example of social network, there are a lot but I wanted to explain a little bit these. I know that my explanation is so short but if I wold explain it well I could make another Treball de Recerca!
