The global COVID-19 pandemic has accelerated the popularity of video games and online-gaming platforms. However, little research is devoted to understanding how the pandemic has affected gamers, especially live-stream broadcasters. Therefore, our study aimed to evaluate the impact the COVID-19 pandemic has had on established streamers on Twitch. By using a longitudinal time-series design and focusing on a large sample (N = 23,019) of broadcasters, we were able to determine the initial as well as prolonged effects of the pandemic on their streaming behavior. Our results suggest that the pandemic was a game changer for the target group, especially in regard to their choice of game settings and their focus on non-gaming content. Relating the data obtained from the target group of established streamers to the general platform data, we discuss the pandemic-related platform dynamics
