When did they quit putting picture tubes in tv?

There isn't a single definitive date when picture tubes were completely eliminated from TVs. The transition was gradual, with CRT (Cathode Ray Tube) televisions being replaced by LCD (Liquid Crystal Display) and later LED (Light Emitting Diode) TVs.

Here's a breakdown of the timeline:

* Early 1990s: LCD TVs began appearing, but were expensive and had limited screen sizes.

* Late 1990s - Early 2000s: LCD TVs became more affordable and widespread, but CRT TVs remained popular for budget-conscious consumers.

* Mid 2000s: LED TVs began to gain popularity, offering better picture quality and energy efficiency than LCD TVs.

* Late 2000s - Early 2010s: LCD and LED TVs became the dominant TV technology, with CRT TVs becoming increasingly rare.

* Present Day: While some specialized applications might still use CRT technology, it is no longer a mainstream technology for consumer televisions.

Therefore, it's more accurate to say that CRT TVs gradually faded out between the late 1990s and early 2010s, rather than having a specific "quit date."
