who invented the first tv in the world

The invention of the first television is attributed to several inventors and pioneers who contributed to its development over time. However, the widely recognized credit for the first practical television system goes to Scottish engineer John Logie Baird. Baird demonstrated the first working television system on January 26, 1926, in London. His system used mechanical methods to scan images and transmit them as television signals.

Simultaneously, other inventors such as Philo Farnsworth in the United States were also working on electronic television systems. Farnsworth is credited with developing the first fully functional all-electronic image pickup device (video camera tube) and demonstrated his system in 1927.

Thus, while Baird is often credited with the first practical demonstration of television, the development of television technology involved contributions from multiple inventors and engineers across different countries during the early 20th century.
