The invention of television is credited to multiple inventors through different stages. John Logie Baird, a Scottish inventor, created the first mechanical television in 1925 and was the first to demonstrate moving images on television. Philo Taylor Farnsworth, an American inventor, developed the first all-electronic television system and was granted the first patent for television by the U.S. government in 1927. Additionally, Paul Nipkow, who invented an early mechanical system called the electric telescope in 1884, is sometimes credited as a pioneer in television technology. In summary:

• John Logie Baird invented and demonstrated the first mechanical television in 1925.
• Philo Farnsworth invented the first fully electronic television system, successfully demonstrating it in 1927.
• Paul Nipkow created an important early mechanical scanning system in 1884.

Thus, while Baird is often credited with inventing the first working television, Farnsworth’s electronic system is considered the precursor to modern television technology.
