Better still, Vestigial Sideband!

You're both wrong. It is VIRTUAL SIDEBAND

Nope - VSB, as commonly used in broadcast television,
most definitely stands for "vestigial sideband" - a form of
AM in which the carrier and part of one sideband (in this
case, the lower sideband is the "vestigial" one) are retained,
along with one full sideband which carries the information
(in this case, the upper sideband, which carries the luminance
(Y) video information).
