What feature allows users to share short videos and stories on platforms like Instagram and Snapchat?

The feature that enables users to share short videos and stories on platforms like Instagram and Snapchat is known as Stories. This functionality allows individuals to post images and short videos that disappear after 24 hours, creating a sense of immediacy and encouraging more genuine interactions. Stories are designed to provide a snapshot of a user's day-to-day activities and can include various engaging features such as filters, stickers, and text overlays.

While other features like Reels also allow for video sharing, they are typically longer and meant for more polished, permanent content. Messages and Posts do not offer the ephemeral storytelling aspect that Stories do, which is a key component of user engagement on these platforms.
