It was described as “the wonderful world of color” in the title of an early television program.

On March 25, 1954, the Radio Corporation of America began to manufacture color television sets at its Bloomington, Ind., plant.

It initially built about 5,000 of these sets, known as the model CT-100 color receiver.

They retailed for $1,000 apiece.

These sets with 12-inch-wide screens didn’t receive much use that year, as colorcasting was severely limited at that time.

It would be difficult to imagine life without color television today.
