TDN2

TDN2 is the secondary state-owned television channel in Calebria, managed by TDN and overseen by RTDN. The channel was first established as an experimental UHF TV channel on channel 47 in the mid-1960s, before being officially launched on June 15, 1967. TDN2's programming focuses on a variety of entertaining content, including talk shows and other engaging programs.

1964-1967
During the period between 1964 and 1967, the channel had sporadic experimental broadcasts, mainly consisting of retransmiting TDN's programming. However, on some occasions, it broadcasted events and other content that were not part of TDN's programming. The channel rarely used its logo on screen and instead, it was mostly featured in newspaper ads and programming schedules.

1967-1972
On June 15, 1967, the channel was officially launched as a secondary channel of TDN, under the name Señal 2 de TDN. It began by re-airing some of TDN's programs with a time delay, while also introducing its own original programming.

1977-1983
On May 4th, 1977, color television broadcasting began in Calebria. On this day, TDN and Señal 2 de TDN were rebranded as Cadena 1 de TDN and Cadena 2 de TDN, respectively.

1997-2001
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.
