Vlogging
Alternatively referred to as a vodcast, vlog or video blogging, vlogging is similar to a blog or podcast where a personal video is created by one or more people that covers something they are interested in or something about their personal life. Today, many of the blog services (mentioned on the blog definition) also support vlogs. In addition to those services, blip.tv, freelog, Justin.tv, Mefeedia, YouTube, and videobloggers.org are some other services that support this technology.
