Southern Broadcasting Network of Davao launched SBN Channel 21, the first local UHF TV station in Metro Manila since 1992. It was then known as World TV 21 by Kampana Television Corporation, which provided programming content from ABC, CNN and ESPN on this channel then. 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.
