Imagine turning on a TV and seeing just a tiny, gray face. That is exactly what happened on October 2, 1925. A Scottish inventor named John Logie Baird showed the world its first television picture. Baird did not work in a fancy lab. He built his device from everyday objects. He used a hat box, a pair of scissors, some darning needles, and a bicycle light lens. The machine was held together with glue and string. His first moving image was the face of a ventriloquist dummy named Stookie Bill. The picture was only about thirty lines of resolution. Modern TVs show over a thousand lines. But in 1925, sending any image through the air was remarkable. Baird's system used a spinning disk with holes in it. Light passed through the holes to create a picture one line at a time. This was called mechanical television. Later, electronic television replaced it. But Baird proved that the idea was possible. He changed how people would receive news, watch stories, and learn about the world.
