The increasing use of social networks is noticed and the question of their excessive consumption is raised. Therefore, the subject of this paper is digital habits of using social networks in selected generations, and the results may vary from very infrequent consumption to addiction. This paper focuses on three platforms, that is social networks based on video content - Instagram (Reels), YouTube, and TikTok, with a focus on four generations - Baby boomers, Generation X, Generation Y, and Generation Z. The main purpose of this paper is to analyze the users' social media digital habits through the aspect of video content, and their frequency and length of usage. The theoretical part will be based on available scientific and professional sources of literature, and the empirical part will be based on primary data obtained by survey research. The research will be conducted on a sample of Croat social network users, with a focus on four generations. The obtained data will be analyzed using appropriate statistical methods. The habits of users of three social networks competing in the video content segment will be analyzed. TikTok is a fast-growing platform that has achieved enviable results in a very short period and completely changed the way and frequency of consumption (Brandastic,2021). Instagram, which has been around for a long time and has already made a revolution with Story - a feature that was the forerunner of shorter videos, suddenly found itself in the position to share the space with a new and very serious competitor and had to adapt with its new feature - Reels ( Kalogeropoulos, 2017). Finally, we come to the native among the video content, still a completely free platform, which convincingly leads in watching longer videos - Youtube.
