The widespread use of the Internet and social media has contributed to the application of their tools in creation of diverse forms of multimedia art. At the same time, online platforms have become a space for the location and distribution of new art objects on par with established physical spaces for the presentation of such objects. Over time, social media has retained its key functionality of interaction with the platform, but the algorithms that personalize user’s exploration of the platform and mechanics that let users influence content within the platform are constantly changing. The objectives of this paper are to provide a method for uncovering the hidden algorithms and capabilities of virtual services, and to describe exactly how shifts in platform policies and user interaction capabilities affect trends in content production. The strategy of concretization based on the history of a certain genre allows us to identify general trends in the transformation of platforms and identify reactions to them from micro-communities that are associated with the production of artwork. As a result of YouTube algorithm changes and their appearance on VK, we can observe a displacement of local projects in favor of commercialized content, and artists tending to concentrate more on their micro-communities, rather than on the public community. This paper will be useful to researchers of media platforms specializing in interface philosophy, and also for those who are interested in multimedia art on the Internet.
