Southern Broadcasting Network of Davao launched SBN Channel 21, the first local UHF TV station in Metro Manila starting 1992. It was then known as World TV 21. The idea is to bring back programming similar to the forcibly shut-down FEN Channel 17 of the former Clark US Air Base a year earlier due to the eruption of Mt. Pinatubo.

This partnership ended in March 2, 2011, as Solar transferred ETC to RPN. As a result, SBN renewed partnership with Solar Entertainment to create the news network Talk TV, and since October 30, 2012, it is now known as the Solar News Channel (now 9TV), the first 24-hour English news channel on free-to-air TV.
