Vladislav Fesko/Operating System Mockups 1

Operating System Mockups 1 is the first Vladislav Fesko's OSM episode. It was uploaded on his OSM channel on YouTube in June 24, 2021.

This video has been planned many times, but it always was cancelled and delayed by the creator. The first attempt of creating it was in July 2019. However, Vladislav cancelled it later.

Since May 2020, it was planned to be named as OS & Program Mockups Collection. It was cancelled several times. Later, the creator stated that OS & Program Mockups Collection will officially be cancelled in October 2020 and it'll be named OS Mockups 1 instead.
