The podcast is quite long (36 minutes), so I'll give a rough outline of what I've spoken about.
3': How we address celebrities in TV (Kamal sir, Rajini sir etc.)
5': Lollu Sabha. A historical moment - Pokkiri's parody - Bakery.
12': "Experts" in TV
15': Nayyandi durbar, Ari Giri assembly
17': Standup comedy in Tamil TV channels (Kalakka povadhu yaaru etc.)
23': Internet's influence on mainstream media
26': Lack of Tamil social commentary in audio-visual formats in the internet.
30': Mainstream hangover in non-mainstream mediums.
34': Interviews in Kumudam.com
Aside: Lollu Sabha issued an apology the week after 'Bakery' was aired. But the sentences were structured in a way that it was obvious that they were being sarcastic about the apology. It's good to see that these people not only have the guts do such parodies but the wit to deal with potentially serious repurcussions.
