John Baird demonstrated the first moving pictures with a tv system that is similar to Nipkow's disc based system.He used 30 lines along with the idea of reflecting light instead of silhouettes to publicly demonstrate the TV. The image he used was a human face. http://inventors.about.com/od/britishinventions/a/JohnBaird.htm -
