This page is a list of the experimental television stations before 1946. After 1945 (in the United States) the television frequencies were opened up to commercialization and regular broadcasts began. Regular broadcast television start dates vary widely by country; in many regions, initial broadcast video deployment was delayed due to mobilisation for World War II.
(Note: The listing of current broadcast channels for these stations is not up-to-date as many low-VHF stations have moved to UHF frequencies as a result of digital television transition. This is less of an issue in the United Kingdom because of its all-UHF system, but most early US broadcasters were on affected channels before analogue shutdown. Very few full-service North American broadcasters remain on physical channels VHF 2-6 digitally due to impulse noise problems and strict limits on maximum transmitted power at these frequencies.)
