Video blogging, sometimes shortened to vlogging (pronounced 'vlogging', as opposed to 'v-logging') or vidding or vidblogging is a form of blogging for which the medium is video, and is a form of Web television. Entries often combine embedded video or a video link with supporting text, images, and other metadata. Entries can be recorded in one take or cut into multiple parts. It is also a very popular category on YouTube.

Video logs (vlogs) also often take advantage of web syndication to allow for the distribution of video over the Internet using either the RSS or Atom syndication formats, for automatic aggregation and playback on mobile devices and personal computers (See video podcast).

On January 2, 2000, Adam Kontras posted a video alongside a blog entry aimed at informing his friends and family of his cross-country move to Los Angeles in pursuit of show business, marking the first post on what would later become the longest-running video blog in history. In November of that year, Adrian Miles posted a video of changing text on a still image, coining the term vog to refer to his video blog. In 2004, Steve Garfield launched his own video blog and declared that year "the year of the video blog". In an effort to fulfill this prediction, Miles and Garfield soon joined their online colleagues Jay Dedman, Peter Van Dijck, Andreas Haugstrup Pedersen, and Christophe Bouten in creating a group on Yahoo! Groups devoted to video blogging.
