TDN1

TDN1 is the primary state-owned television channel in Calebria, managed by TDN and overseen by RTDN. The channel has come a long way since its experimental broadcasts between April and August of 1953, until it's official inauguration on August 17, 1953, as the first television channel in the country.

In 1997, TDN's channels underwent a major rebranding effort, simplifying their names to TDN1, TDN2, TDN3 and TDN4. This change has remained in effect to the present day.
