Soho Marks 100 Years Since Baird’s First Television Demonstration

The centennial prompts a reassessment of Baird’s 30-line mechanical system within television’s shift to electronic standards.

Overview

  • At Bar Italia on Frith Street, John Logie Baird’s grandson unveiled a World Origin Site plaque and opened a new Baird Room honoring the 1926 demo location.
  • In January 1926, Baird showed journalists a working mechanical television in his Soho workshop using spinning disks to scan images at just 30 lines of resolution.
  • The BBC engaged with Baird’s system early on, but the UK ultimately adopted EMI’s 405-line electronic standard, later transitioning to PAL color in the late 1960s.
  • Historians describe Baird’s method as ingenious yet limited, noting early broadcasts suffered about a 54-second delay that frustrated engineers seeking truly live transmissions.
  • Anniversary coverage has renewed hobbyist interest, with enthusiasts able to recreate Baird-style sets using printable scanning disks and simple components.
