Substack has launched a new vertical video feed under its 'Media' tab, positioning itself to capture audience interest as TikTok faces another potential ban. This feature allows users to upload videos of up to 10 minutes, similar to TikTok's format, and enables content discovery for both subscribers and non-subscribers. The move aligns Substack with recent trends in social media, joining platforms like X and Bluesky in adopting a TikTok-like experience. With TikTok's future uncertain due to legal pressures, Substack aims to enhance user engagement and broaden content access.
