Consumer Electronics
In the past, consumer electronics manufacturers would emblazon radios and TV sets with "Instant On" or "Instant Play" decals. In series filament sets, instant on was accomplished by adding only a silicon diode across the power switch to keep tube filaments lit at 50% power; the diode was placed such that the typical half wave rectifier of the day was reverse-biased. Instant on advantages included near-instant operation of the television or radio and potentially longer vacuum tube life; disadvantages included energy consumption and risk of fire. Most solid state consumer electronics are inherently instant on, so the moniker survived into the early solid state era to differentiate a product from its vacuum-tube based brethren (with CRTs being a notable exception).

Famous quotes containing the words consumer and/or electronics:
“The poverty of our century is unlike that of any other. It is not, as poverty was before, the result of natural scarcity, but of a set of priorities imposed upon the rest of the world by the rich. Consequently, the modern poor are not pitied ... but written off as trash. The twentieth-century consumer economy has produced the first culture for which a beggar is a reminder of nothing.”
—John Berger (b. 1926)
“We live in a highly industrialized society and every member of the Black nation must be as academically and technologically developed as possible. To wage a revolution, we need competent teachers, doctors, nurses, electronics experts, chemists, biologists, physicists, political scientists, and so on and so forth. Black women sitting at home reading bedtime stories to their children are just not going to make it.”
—Frances Beale, African American feminist and civil rights activist. The Black Woman, ch. 14 (1970)
