An audio slideshow on John Logie Baird, published by BBC Scotland on the day digital switchover was completed in Scotland. Iain Baird, JLB’s grandson and curator of TV at the National Media Museum in Bradford says that not only did his grandpa transmit the first television picture, he also had working models of 3D TV, HD TV and colour TV in the 40s. What a guy … and he’s from my home town, Helensburgh!
