Jerome Halphen said that Sanyo made a small TV with this type of tube, and I am certain that I did see a small 3" Sanyo TV in a pink case on a pedestal for sale on eBay a few years ago. I did not know about the Beam Index technology tubes at that time, and did not pay too much attention to that set because it was a Sanyo - I have never been a fan of Sanyo products. I really hope that 1 of these sets surfaces again just to prove that Jerome and I are not crazy!
From Wikipedia:
Sanyo used the bright images to make a new style of tube they called the "lollipop".[12] It used an electron gun arranged at right angles to the display, extending down instead of to the rear. The result was a 3 inch display only 1½ inches deep, although it was several inches long. They demonstrated the system in a small television similar to the Sony Indextron.
