ARD and ZDF have published their current online study for 2015 and, of course, also address the use of social networks. While the study provides many insightful results, it also has a problem in the clear allocation of online activities. This is not easy with such a survey and shows in parallel how extensive and complex social networks have become.

Video usage < del > Everywhere and ubiquitous

According to the survey, 61% of respondents aged 14 to 29 use Facebook at least once a week. In the survey, Facebook was also considered separately for the consumption of Facebook videos. Here, however, the study comes to only 30%. That's half of the Facebook users surveyed. In reality, the two results would have to be almost identical, since there is almost no way around native videos on Facebook.

A total of 82% of the surveyed videos are viewed on the Internet. Thus, moving image is one of the most important content formats independent of channel and application. Consumption of videos on Twitter, Instagram and other social networks was not included in the study. In reality, the figure is likely to be even higher.

Social media use in Germany well ahead of Twitter

When we talk about social networks, the ARD / ZDF online study talks about online applications. WhatsApp is by far the most used communication channel with 83%. Although the question also includes other mobile messengers, WhatsApp is the clear front-runner in Germany. Facebook follows by a relatively wide margin, coming in at 61%.

The study shows once again that Twitter is having trouble establishing itself in Germany. Of course, awareness is rising and more and more people have heard of Twitter. But when it comes to active use, Instagram has already overtaken Twitter. Or rather, leave it at that. While 26% of respondents use Instagram at least once a week, only 5% use Twitter. And this in the target group of 14 to 29 year olds. The results represent the massive growth of Instagram in Germany. This is a development that we have never seen on Twitter in this form and that will be increasingly difficult for Twitter to achieve.

However, it is also clear from Instagram that younger users are much more dominant than on other social networks. 45% of 14- to 19-year-olds use Instagram and only around 16% of 20- to 29-year-olds use it. It's a similar story on Twitter. So you could say Facebook is the social network for all ages, and the older we get, the less likely we are to try other networks and apps.

Social networks cover a large part of online activity

The study talks about online activities. One activity is the use of social networks. A large part of the other activities may not (yet) be dominated by Facebook and Co., but social networks have also positioned themselves in other fields and are developing into true all-rounders. Emails are increasingly being replaced by fast communication on Facebook, Twitter, LinkedIn and mobile messenger.

Pinterest is a visual search engine and YouTube is the second largest search engine in the world. Articles and messages are read directly on Facebook and LinkedIn, and people no longer have to visit the websites of media companies. Online banking? In the US, users can send money to contacts via Facebook Messenger, Line and Snapchat.

's digital maps are integrated into Facebook Places pages and the local Facebook search includes more and more information and recommendations from friends. Social networking sites and buy buttons can also be found on Facebook, Twitter, Pinterest and Instagram. In this style it continues with all mentioned online activities. Social networks are everywhere and their influence is growing.

The company said in a statement: 'We are pleased to announce that we have reached an agreement with the Department of Health and Human Services. ARD / ZDF Online Study 2015 offers many more exciting results and is available for free download.
