I think that GMA had to forcibly change channels when Canal 7 started in 1970. Also ABS-CBN in the real world was the product of a merger. ABS here should be channel 2 and CBN channel 4. GMA moved there also to fill in the gap CBN left in 1967 upon the merger.

A name for the Banahaw Broadcasting Corporation (1973-1986) is also needed.
