Discussing the ever evolving medium of radio at this week's Radio Asia conference in Bangladesh, the ABC's Andrea Ho reminded delegates that radio was the first social medium and, if used well, is able to challenge the new social media of today.

“Humans are hard wired to talk. We talk to share. Sharing is at the heart of society.

“Radio with talkback was the first social medium,” she said.

Andrea Ho reminded participants that radio was first in its use of talkback, something to be remembered as radio takes on the new social media platforms.
