s in its CTC-2 chassis (known as "Merrill" to the marketing department) was the most complicated electronic device sold to the general public at the time of its release. After initial sales to
early adopters, the rest sold poorly, even after a price cut. Many were donated by RCA for training purposes to trade schools and technical colleges, the source of most of today's survivors. RCA sold the CT-100 at a loss. RCA later recalled the CT-100, replacing many of them with a newer 21-inch model.

Early NBC Living Color programs included ''
An Evening with Fred Astaire''.
The CT-100 was created in 1954, before the
NBC Peacock logo existed.
RCA CT-100 sets are extremely sought-after by electronics collectors and restorers, with restorers often spending thousands of dollars to obtain or repair a set.
It is believed that RCA only made 4000 CT-100 receivers. Around 150 survive, but only 30 are restored and working. The

Spats Bearhas a restored and working set in his collection. One reason for the rarity of surviving sets is that the RCA-developed tri-color cathode ray tube (the 15GP22) that was used in the CT-100 was notorious for its glass-to-metal seals breaking down, causing the tube to lose its vacuum.
It is extremely rare to find tubes that still work. The 15G was a glass tube, but its high voltage connection is a metal ring between the face of the tube and the glass bell or funnel. This is where the leakage often occurs.
