What superior technology eventually replaced John Logie Baird's mechanical system?

Answer

The fully electronic system developed by the EMI-Marconi company

While Baird's mechanical system, which utilized a spinning disc, was historically significant, it suffered from inherent limitations regarding image resolution and flicker. As global research into television technology advanced, the EMI-Marconi company developed a fully electronic system. This electronic approach provided significantly higher fidelity and clearer image quality, which ultimately rendered the older, mechanical method obsolete for high-definition broadcasting.
