The idea of multi-electrode tubes itself was far from new and indeed the Loewe company of Germany was producing multi-electrode tubes as far back as 1926, and they even included all of the required passive components as well. Use was prevalent in televisions because transistors were slow to achieve the high power and frequency capabilities needed particularly in color television sets.
Virtually every AM/FM radio receiver of the 1950s and 60's used a 6AK8 (EABC80) tube (or equivalent) consisting of three diodes and a triode which was designed in 1954. Compactron's integrated valve design helped lower power consumption and heat generation (they were to tubes what integrated circuits were to transistors).

This vacuum tube family was introduced in 1961 by General Electric in Owensboro, Kentucky to compete with transistorized electronics during the solid state transition.
Compactrons simply don't exist in any TV sets designed after 1986.
Manufacture of Compactrons ceased in the early 1990s.
