The correct answer is Internet

The internet has revolutionized our form of communication and social relationships. It has profoundly transformed the way we interact, whether in our families or in the other social groups we belong to. It changed how we live, learn, work, consume and have fun. The internet has brought benefits in the use of technologies with easy access to knowledge, in the collaboration between people and organizations, in social inclusion, and in the creation of values.

At the beginning of the internet, its content was produced by a few. Only those who knew programming techniques could produce content. Most internet users could only navigate between pages. In recent years, this has changed radically, new tools have been created to facilitate the creation of content and to share in very simple ways, whether through blogs, social networks, or videos on. This interaction between Internet users was very enriching for the internet, strengthening its field of penetration everywhere. We see people in all corners of the world creating blogs or photoblogs to keep in touch with their more distant relatives and friends or simply share ideas with the whole world, without the geographical limitation of the past, and it can simply be all done from a mobile device.
