The most important conclusion is that producers must ultimately sell their programs to sponsors, that this is an explicit understanding which guides all program content and how the message is presented.

That Public Broadcasting is more that 50% funded by these same corporations which leads to the same programming constraints.

That the cost of an ad or ad campaign is so high that only these mega-corporations can pay and play. So they dominate the airwaves. It is essentially private ownership of the news.

That the public doesn't realize that free speech is not a right we enjoy equally since the most pervasive and powerful communications medium is controlled by so very few.

Mander gives a lot of statistics for viewers and hours viewed (5 hours per day is average!) but I posted not to go off on a rant about TV or the MSM but to help us understand that what we regard as the "news" is highly filtered to reflect the view of these very few, very large corporations.
In this regard we are not unlike Al Jazeera. And... we think of Al Jazeera as presenting highly selected and inflammatory news. I guess they have different sponsors <g>.

Understanding this sponsorship ratio is important. Quite literally, TSWHTF before PO gets honest representation at 6 P.M. And even then it will be filtered. So it truly is up to places like TOD to educate the public. As in New Orleans, help isn't on the way.
