Hi everybody. Today we will look at a topic that is rather meager in itself and, by and large, is not worth a separate analysis - the development from Web 1.0 to Web 3.0. However, as a simple plan for understanding the development of the world Wide Web and related technologies will be useful. 

Well, let's get started. Let's just say that the initial stage of development was Web 1.0 (this stage dates from about 1991-2004). A distinctive feature of this stage was one-way interaction, pure consumption of content, without any influence on it. There were thousands of sites created by people or companies that were visited by users, but they were strictly designed and, by today's standards, empty: a complete lack of advertising, interactivity, interactions between site visitors or visitors with the creators. If personal pages of users existed, they were only a way of authorization on the resource.

Things have already gone much more fun at the 2.0 stage. Web 2.0--the concept first appeared in 1999, but it only came into circulation in 2004, when it was applied in a speech by Tim O'Reilly and Darcy Dinuchi at a conference that later became known as the Web 2.0 summit.

Feedback appeared on the resources: comments, ratings; interaction between users; collection of information for the algorithm (both from one user and all together); the resources themselves became "livelier", "more mobile"; users received their pages and instruments of influence on content and authors, as well as the creation of their own was simplified content.

Well, the most relevant and interesting point is Web 3.0. This is exactly what we are seeing on the web now. If in the first version the goal was the exchange of information, in the second version-interaction, then the goal of Web 3.0 was immersion. The use of 3D has also become a distinctive feature: websites have become more voluminous, games have become one of the ways to get information and study material. There was a deepening of the immersion of users, as well as their influence on the resource increased. Artificial intelligence has become more actively used to better meet the needs of the user. All devices are connected to the Internet and, often, connected, which makes the network ubiquitous, and the user's immersion deeper.

"I don't have a mouth, but I have to scream." If anything, this is the name of the game, but we will not talk about it, but about another phenomenon characteristic of Web 3.0-- VR chats. One of the most famous representatives of this genre is "Second Life" - a project where users interact not only with each other, but also with the world around them. Such functionality can be used for various purposes, however, we will consider an application for learning a foreign language. The functionality allows you to create completely different situations, do game tasks, which increases immersion and interest. Let's start with the fact that the "Second Life" allows you to liberate yourself, treat communication with other users better, and if you interact with native speakers in order to learn it, you are easier to enter into a dialogue, less afraid of making a mistake. In addition, the game allows you to create different situations: in the cinema, in the store, etc., which gives more immersion, improves memorization. From above, we will add various game formats that raise interest. You can continue for a long time, but I'm already tired, so let's stop there.

Thank you all for your attention. Peace to all.
