Although Steam is basically called a gaming platform, over the years, it has also become a video hub. It included his own documentary and even major Hollywood releases, but today Valve has announced it's going to "refocus." According to a blog post, he went out of the "Videos" section of the Steam Store menu and said that content that is not related to the games will also come out in the coming weeks so that it is no longer available for purchase. However, if you purchased a movie or a video from Steam, you will be able to view it in the same way as before.
This does not mean that you will not see videos right now on Steam, but they will be related to the games and can be found under the pages of these games or through search. As the company changes its content policy and faces a new challenge from Epic, it's probably time to reassess its efforts and focus on the fact that gamers use the most demanded Valve.
