This is a list of when the first publicly announced television broadcasts occurred in the mentioned countries. Non-public field tests and closed circuit demonstrations are not included.

This list should not be interpreted to mean the whole of a country had television service by the specified date. For example, the United States, Great Britain, Germany, and the former Soviet Union all had operational television stations and a limited number of viewers by 1939. Very few cities in each country had television service. Television broadcasts were not yet available in most places.
