In 2021，western social platforms continue to explore more comprehensive development possibilities. In terms of content，western social platforms show an obvious shift to audio and video. Platforms such as Instagram and YouTube have launched short video functions，and platforms such as Spotify and Facebook have begun to explore the possibility of copying the Clubhouse audio social model. At the same time，each platform has also actively taken financial incentives，copyright protection，and other ways to attract content producers. In terms of revenue，western social media have tried to enrich the existing revenue model in 2021 and continue to explore shopping and live streaming services on the platforms. In terms of governance，in addition to misinformation and privacy issues，following Frances Haugen’s revelations on Facebook，the protection to teenage users has also become the focus of attention on various platforms.
