I urge you to read David Sirota's Pando Daily story "The Wolf of Sesame Street: Revealing the secret corruption inside PBS’s news division." Here are the first two paragraphs:
On December 18th, the Public Broadcasting Service’s flagship station WNET issued a press release announcing the launch of a new two-year news series entitled “Pension Peril.” The series, promoting cuts to public employee pensions, is airing on hundreds of PBS outlets all over the nation. It has been presented as objective news on major PBS programs including the PBS News Hour.
However, neither the WNET press release nor the broadcasted segments explicitly disclosed who is financing the series. Pando has exclusively confirmed that “Pension Peril” is secretly funded by former Enron trader John Arnold, a billionaire political powerbroker who is actively trying to shape the very pension policy that the series claims to be dispassionately covering.
You really, really have to go read the whole thing.
