Hello. I am a student wanting to go into broadcast and have some research to do.
I hope someone in the radio or TV industry can help answer some of the
questions I have:

1) What does the Media House actually do aside from selling media?
2) I understand that they help put a package up, how to they do that
and where do they get info to do that?
3) How do Media Houses get updated info from TV/Radio stations on the
available spots they have? What is the universal way media houses get
this realtime info? What if a spot that was available is sold by
someone else and you then booked it for your client?
4) Can anybody contact the station and purchase air time directly?

TQ!
