Startup Idea : TVad Exchange

An online service where TV channels are subscribed by periodically submitting (or automated fetch) their available time slots for TV spots, banners and so on. A pool of TV ad slots from various providers. The site also gathers TV ratings for channels, detailed viewer demographics, social media penetration stats of the shows that are aired on a particular channel, popularity index, and target audience suggestions, tags, categories, keywords and so on. So the user (media agency, ad agency or the client) can see the price index like a stock exchange (locally & internationally), preview their ad or even create custom focus group by using IPTV, book, pay, cancel and so on. Government officials can monitor the ads before the commercials are aired for audit, if that is ever needed. It is kind of Google Ad suite for TV.
