Hmm, I never heard of a TV that scanned vertically.  Are you sure you 
did not have the TV sitting on its side?  ;)

What you may be referring to is the fact that a Trinitron display uses 
an Aperture Grill instead of the conventional Shadow Mask.  The Aperture 
Grill has complete vertical red, green, and blue phosphor stripes top to 
bottom.  The picture creation still scans left to right because that is 
how the analog signal is coming in to the TV.  Otherwise, the complete 
image would have to be stored and rotated 90 degrees in a buffer before 
the guns spit out the image.  I can't imagine what timing problems that 
would have.

Here is a link with a bit more information:

Computer Trinitron displays use the same technique.
