Online video platforms allow users to upload, share videos or live stream their own videos to the Internet. These can either be for the general public to watch, or particular users on a shared network. The most popular video hosting website is YouTube, 2 billion active until October 2020 and the most extensive catalog of online videos. There are some countries in the world placing restrictions on YouTube, instead having their own regional video-sharing websites in its place. Other popular video platforms include TikTok, Bilibili, and Twitch.

List of online video platforms in the context of Video chapter
Video chapters on online video platforms divide the videos into sections, with each section having a specific "chapter title", most notably YouTube. Most services offer a manual way to add chapter sections and title them, several platforms also offer automatic tools for this. The purpose is to aid the navigation of the video as well as to encourage video creators to structure the videos coherently. Both of these goals aid users in general, and in particular can be beneficial to persons with disabilities.
Online learning platforms - such as Coursera - were some of the early adopters of chapters marks in the videos that form part of their curricula as a way to aid navigation, and convey the structure of the lectures and their subject matter.
