Things I would like to find out

For any country,

1. what's the average wage for a journalist?
2. what's the average wage for a journalist working in the public service broadcaster?
3. is there a trade magazine in journalism or communications?
4. is there some magazine or annual agenda which shows the editors of the various television news desks? (Like Benn's Media in the UK, except better; more like Agenda del Giornalista in Italy)
5. have there been any surveys of journalists?
6. are the names of television news editors ever mentioned in the non-specialist press? Would someone interested in politics know them?
7. are the names of television executives followed by party labels in brackets? Would someone interested in politics know these affiliations?
8. How does one become a journalist for the public service broadcaster?
9. Where did the first PSB journalists come from?
10. Were the first PSB news broadcasts produced in-house, or did they rely on wire-services (AP, Reuters, TT, etc.,)?

Boring to you, life-blood for me.
