Today marks the 100th anniversary of the first public demonstration of television. This pivotal event, spearheaded by John Logie Baird, occurred in London on January 26, 1926. Baird's early system utilized an electro-mechanical approach, employing spinning discs and lenses to transmit images. The demonstration to journalists showcased his innovative technology.

Baird's journey to this moment was marked by setbacks, including health issues that initially prevented him from joining the military. His workshop at 22 Frith Street hosted the groundbreaking demonstration. The technology involved a rotating disc with lenses, a shutter, and a light-sensitive cell, which transmitted images. The limitations of early TV were clear.

Despite the early skepticism, Baird's invention paved the way for modern television. Following the demonstration, Baird continued to innovate, experimenting with color and 3D television. The BBC began broadcasting in 1930, although the technology would soon be eclipsed by Marconi-EMI's superior electronic system.

Ultimately, Baird's mechanical system was phased out, but his pioneering efforts are still recognized. His legacy is celebrated with plaques in London, commemorating the birthplace of television. Today, the location of the demonstration is a cafe, Bar Italia, offering espresso and pizza to celebrate the centenary.
