The first name for the small site was Thefacebook. Only university students could. After Mark decided to expand the audience of the site, other students from the American city of Boston were allowed to register. A little later, it was possible to create an account for any student who studied in America. In order to register, you had to have email on the .edu domain - common for the educational system. And already in September 2006 all Internet users got access to the site. To register, you had to be over 16 years old, and also have an email address on any of the existing domains.

Now the student project has grown to incredible proportions, it is unlikely that Zuckerberg himself imagined how far his desire to unite the student community would come.

In addition, VK does not require an additional mobile application in order to communicate.

Also, VKontakte has a much stronger and more developed Russian-speaking community than a similar social network of their America. And the abundance of content in an understandable language attracts users from the CIS countries.

Like a foreign site, VKontakte was originally a social network in which students and graduates of Russian universities communicated. The site positioned itself as a platform for quick and convenient communication, finding friends and trying to be modern and try things that were previously inaccessible to users of the Russian Internet. It is now the most popular social network in Russia.

Now it is one of the most popular sites in the post-Soviet space. Almost a billion users from all over the world are registered there. Registration for the site is free and available by phone number. Linking a page to a number is one of the security requirements so that the user's page cannot be captured by intruders and turned into a platform for sending spam, and malicious links and fraud on behalf of that person.

Initially, the social network was available to students and recent graduates from Russian universities. However, in order to register, it was necessary to receive an invitation from a user who already has a profile on the network, and then indicate his real name and surname. However, soon the registration was opened and an advertising campaign was launched in order to attract new users. Since then, the social network VKontakte has only been developing and gaining popularity.

Twitter

Twitter is a social network for exchanging short messages and small media files with users. The name comes from the English to tweet - to tweet, chat, which is why the social network has a logo - a bird. The format of this social network is called microblogging, the user does not pay to publish posts and read their subscriptions in the feed.

Twitter was created by Jack Dorsey in 2006, after which Twitter began to rapidly gain popularity, since at that time it was the fastest and most convenient way to exchange information and posts with users. However, initially the social network had a limit on the number of characters that can be written in one message - 140. Later, the developers increased this number to 280 characters.

Now the service has almost half a million registered accounts. These are both ordinary users and stars who use it as quick way transmitting information to your fans, answering their questions and expressing your opinion about current events. There are also accounts of brands and music groups.

Pinterest

Pinterest is a social service. In it, users can add images to collections by topic and share them with other users. The main difference from Instagram is that Pinterest is a network where very aesthetic pictures of any thematic focus are thrown off. So, there are images of clothes, cities, food, as well as a selection of paintings and photos of stars. In addition, users often upload their drawings, tattoos, and more there.

Pinterest is used by many as a source of inspiration. It can be compared to Google images, there are also a lot of them, but they are of higher quality, selected by users and worked out.

conclusions

As you can see, with the development of social networks, now the possibilities of each person are almost limitless. A person can develop himself and his abilities, turn his profile into a platform for business or blog and develop on this.

However, you should never forget about safety on the Internet, as well as the fact that in addition to social networks there is a real life that needs to be developed and established with no less diligence than virtual page online.

Unfortunately, dependence on social networks, the Internet, likes, positive comments from complete strangers happens too often. And an overly reverent attitude to the social network, the substitution of virtual life for real life leads to depression, the development of complexes and can seriously negatively disturb the psyche.
When registering on any social network, be clearly aware that this will take you a lot of time that could be spent on self-development, and you should also understand that social networks are entertaining as much as they are frustrating. Give yourself your word in advance not to worry about stupid people online, clearly limit visits to social networks per day and try to spend time online not only for entertainment, but also with benefit - subscribe to interesting and informative blogs that will broaden your horizons and allow you to become more social and an active person.

The five most popular social networks in the world have not changed in recent years. Three of them - Youtube, Facebook, Instagram - are heard in Russia as well. Two Chinese social networks complete the list of leaders. They did not spread their influence in Europe and the United States, but took the lead thanks to the number of active users from Asia.

Dynamics of development of social networks 2004-2019

A very revealing video about which networks and what kind of content are becoming more in demand.

Each social network differs in terms of the contingent of users, the nature of the content, the specifics of working with the region. Different target audiences require a different approach, so differences between social networks are necessary when planning a promotion.

The main thing is live users

When comparing social networks with each other, it makes sense to take into account only active users, and not the number of created accounts. In most social networks, the process of creating additional accounts is as complicated as possible - a mandatory binding is established to a phone number, mail, accounts in other social networks. Owners of pages that are not logged in daily are asked to protect their data with additional bindings the next time they enter.

Maintaining business accounts on social networks and a separate budget for SMM are becoming the norm for large companies. The most popular social networks have additional functionality for registering and maintaining business accounts, and also offer to use integrated systems for analytics of attendance, activity, and the effectiveness of promotions.

The most popular social networks in the world

According to research by analytical company Statista, the most popular social networks in the world, ranked by the number of active users (in millions), as of October 2019:

China's largest social networks Qzone, QQ and WeChat have over 570 million users in the Asia-Pacific region. Instagram and Twitter are popular mainly in Europe and the USA. Oddly enough, in terms of activity in social networks, Europe is still lagging behind even Russia, so European social networks are not visible in the top 10.

Social networks: a list of popular in Russia

Medialogia conducted a study on platform mentions in social networks in August 2019. The Russian-language segment of social media was considered (Twitter, VKontakte, Odnoklassniki, Facebook, Instagram, Youtube, LiveJournal, forums and blogs). Data were taken into account without self-citation.
The leader in terms of mentions was YouTube - 24.7 million messages, followed by Instаgram - 13 million and VKontakte - 8.2 million.

On the 11th and 12th places were Snapchat - 0.4 million mentions, and My World - 0.2 million, respectively.
Earlier, Mediascope conducted a study on the platform audience, VKontakte with 37.9 million people, Instagram with 30.6 million and Odnoklassniki with 23.1 million in the lead by the number of monthly users
Despite the fact that Snapchat is in eleventh place in terms of mentioning, it became the fifth most popular social network in Russia in the first half of 2019, according to Mediascope data.

What are social networks

The list of popular social networks is headed by platforms for easily accessible content for the user: photos, videos, something that does not need to be read for a long time. If you are promoting a brand on a particular social network, the content must be strictly adapted to the requirements of the audience. Do not try to promote text content on Twitter or Instagram: users of these platforms are used to receiving visual content with only a small amount of text content. Few people delve into the comments under the posts for a long time, the main emphasis should be on visualization, brevity.

Facebook promotion allows for variations with content. The platform is tailored for different content: short messages, photographs with captions are there side by side with designed longreads of a specific topic. There are many communities and opportunities to discuss anything with like-minded people .;

Social media for business promotion: what drives you to make purchases?

Sprout Social, an agency that has researched American and global social networks since 2010, has published a diagram showing what brings users closer to taking a conversion action on a social network.

  • Most users note that they prioritize a quick response from a specialist;
  • Half of brand followers on social media respond positively to promotions;
  • Slightly over 40% expect to see on the company page useful information;
  • 27% of users will want to make a purchase if you show them the “behind the scenes”.

Half of the users surveyed threaten to unsubscribe from the page immediately, and 27% plan to mark the brand as spam and block it if annoying / negative / uninteresting information appears in the public. Reaching an audience and attracting new potential customers requires interesting and useful content that will resonate with target audience... When choosing materials and designing publications, you will have to weed out a lot of unnecessary things.

Social networks are not only a place for people to communicate, but also a platform for working with potential clients, prompt responses and holding promotions to attract the target audience. If you decide to promote your business or product on social networks, remember the basic principles:

  • Better a good promotion on one social network than a bad one on several;
  • The social network chosen for promotion should correspond to the specifics of the brand: it is better to present cosmetics and perfumes through social networks of visual content;
  • Content must match both the social network and the brand;
  • For some social networks, interaction with the audience is critically important, and this is additional costs for the development of promotions, contests, which must be taken into account when making an estimate;
  • Promotion in some social networks has a beneficial effect on promotion in search engines, this is especially true if the social network platform and search system belong to the same company.

Everyone knows only about 2-3 of the most popular social networks. But do not forget that there are many other thematic communities on the Internet, in which people united by common interests or professional sphere are constantly active on a daily basis.
