Tseng 4

Tseng 4 is a Tsengian television channel owned by Independent Broadcasting System (IBS). It broadcasts a wide range of programming from its base at the IBS Complex in Hillsborough, Tseng. It is the second-most watched channel in Tseng behind TBS-1, and is oriented towards both young and adult people.

Early years
Tseng 4 launched on February 13, 1983, and was headed up by Andries Yi's business partner Alan Cheng-Gui.

Upon launch, Tseng 4 quickly took off with a schedule of "youthful" programming. This included exclusive coverage of several international sports leagues, including the UK's and, the US'  and , West Germany's , France's  and Japan's. Their coverage of English, Scottish, German and French association football proved to be especially popular, commentated by former Tseng City Tigers players Melvin Woodroofe and Gary Bronfman, who spoke Mandarin with distinctive English and Brooklyn accents, respectively.

Tseng 4's Saturday morning children's programming block Saturday Hello! became a signature item of the channel and is one of its longest-running features, having been part of Tseng 4's schedule continously since the debut year.

In 1988, as part of IBS' acquistion of the rights to the Tsengian Basketball Association, Tseng 4 began broadcasting games alongside TV0.
