A vlog (or video blog) is a blog that contains video content. The small, but growing, segment of the blogosphere devoted to vlogs is sometimes referred to as the vlogosphere.
Some bloggers have included video content for years. However, vlogging is becoming more common as equipment becomes cheaper and supporting software and hosting and aggregation sites become more prevalent. Both Yahoo and Google feature video sections and many MP3 players, such as the hugely popular iPod , support video.
