Why didn't we have a thriving mass media industry outside Metro Manila?

I'm still seeing comments across social media, arguing why there shouldn't have been a national language at all, or why Tagalog is killing other languages and dialects, among others.

The best way to counter the reinforcement of Tagalog in all levels was through mass media - songs, newspapers, radio, TV, movies, now online streaming - mainly funded by the private sector. That's pretty much what India & Canada did - build media industries and studios along linguistic lines, across multiple cities.

After EDSA 1 only ABS-CBN really pursued to re-establish its presence at the regional level, operating up to 11 regional TV stations at one point. GMA pretty much operates from the same regional stations they established in the Marcos era. Ang PTV ngayon lang nag-e-expand, with new media hubs in Davao and Cebu. No wonder I'm seeing posts of creatives from the provinces moving to Metro Manila, kasi

I've seen footage from the 1960s and 1970s of a thriving media industry in Cebu & Iloilo, with songs, movies, & TV shows entirely in Hiligaynon & Cebuano. What happened to them? Bakit nawala?
