While electromechanical techniques were developed prior to World War II, most notably by Charles Francis Jenkins and John Logie Baird, all-electronic television systems relied on the inventions of Philo Taylor Farnsworth, Vladimir Zworykin and others to produce a system suitable for mass distribution of television programming. Commercial broadcast programming, following years of experimental broadcasts seen only in a few specially-equipped homes, occurred in both the United States and the United Kingdom before World War II.
Inventions are not copyrighted, they are patented. If a patent was filed for televisions, they have expired by now.

The original U.S. television patent was filed by Philo Farnsworth shortly after World War II.
