History of color television

• Color television revolutionized the visual medium, transforming how audiences experienced content and how creators approached storytelling
• The development of color TV technology spanned several decades, involving complex engineering challenges and industry standardization efforts
• This technological leap significantly impacted the entire television ecosystem, from production to consumption

Early color experiments

• John Logie Baird demonstrated the first color television system in 1928 using a mechanical scanning system
• CBS developed a field-sequential color system in the 1940s, but it was incompatible with existing black and white sets
• RCA worked on an all-electronic compatible color system throughout the 1940s and early 1950s
• These early experiments laid the groundwork for future color TV standards and technologies

NTSC color standard

• National Television System Committee (NTSC) developed the first widely adopted color television standard in 1953
• NTSC standard maintained backward compatibility with existing black and white television sets
• Utilized a 3.58 MHz color subcarrier to transmit chrominance information alongside the luminance signal
• Defined a color space using YIQ color model, where Y represents luminance, and I and Q represent chrominance
• NTSC color standard faced challenges with color accuracy and stability, leading to the nickname "Never Twice the Same Color"

First color broadcasts

• NBC made the first coast-to-coast color broadcast of the Tournament of Roses Parade on January 1, 1954
