The document traces the evolution of television from its origins in 1884 when Paul Nipkow designed the scanning disk, an important early component. John Logie Baird later designed other key TV components and made the first public broadcast in London in 1927. Early TVs were large console sets that gave way to smaller, flatter screens in later decades. New innovations included the introduction of color and direct broadcast satellite technology in the 1970s, with few design changes through the 1990s until the emergence of curved, high-definition screens.
