The Tube Music Network, Inc., or The Tube, was an American digital multicast television network. The network was a fully owned subsidiary of The Tube Media Corp., an independent company that was founded by David Levy in 2003. The Tube focused classic and modern music videos in a format similar to the original format of cable networks MTV and VH1, prior to those networks' shift towards long-form entertainment programming. The network also aired occasional commercials and public service announcements, as well as three hours of educational and informational programming (as mandated by the Federal Communications Commission) on Saturday mornings.
