Media watchdogs Support Public Broadcasting (SOS) Coalition and Media Monitoring Africa (MMA) have told communications regulator Icasa to act in the public interest in digital broadcasting migration to avoid marginalising millions of poor South Africans. They warned on Friday at Icasa hearings that millions of South Africans still rely on public-interest broadcasting to make informed decisions about their lives. In a joint presentation to Icasa, which is reviewing the digital migration regulations of 2012, Uyanda Siyotula, national coordinator at the SOS Coalition, and William Bird, executive director at MMA, said large financial interests should not determine how the migration to digital is done.
