Vlog - It's an epidemic

vlog (vlawg; VEE-lawg) n. A blog that contains mostly video content.

"...After blogging came photo blogging and then, suddenly last year, video blogging. Video bloggers, also known as vloggers, are people who regularly post videos on the Internet, creating primitive shows for anyone who cares to watch. Some vlogs are cooking shows, some are minidocumentaries, some are mock news programs and some are almost art films...". (vía wordspy)
