There are several online video hosting services, including YouTube, as well as Vimeo, Twitch, and Youku. In recent years, the platform of internet video has been used to stream live events.

Additionally, internet video has played an important role in the music industry as a medium to watch music videos and gain popularity for songs
Video coding format and Timeline of online video
Practical online video streaming was only made possible with advances in data compression, due to the impractically high bandwidth requirements of uncompressed video. Raw digital video requires a bandwidth of 168 Mbit/s for SD video, and over 1 Gbit/s for FHD video.
H.264/MPEG-4 AVC and MPEG-4
H.264/MPEG-4 AVC is the most widely used video coding format on the Internet. It was developed in 2003 by a number of organizations.
AVCHD
AVCHD, or Advanced Video Coding High Definition, uses one of the more efficient video coding formats. It was announced in May 2006 and since then has grown into a high-quality video format that can compete with other professional forms of media. The AVCHD is geared towards consumer shooters; this is largely because the AVCHD format capitalizes on the H.264/MPEG-4 video that is able to compress video to smaller sizes in order to allow more video to be stored in the same storage capacity.
Flash Video (FLV) is video encoded by Adobe Flash software in order to play within the Adobe Flash Player. Popular in the past, and used by several video sites, including YouTube, the Adobe Flash Player has been replaced by HTML5 and this format has been abandoned.
MPEG-4 Part 14 and MPEG-4
MPEG-4 is known as a sharing format for the internet. In recent years an increasing number of camcorder and cameras began employ it.
