Wisconsin Public Radio’s Home page tells the story:

NOTICE: Due to rights issues, the Ideas Network internet streaming service cannot carry the BBC and CBC programming from 11:30pm to 6am weekdays and 12am to 6am on weekends until the conclusion of the Olympics on September 1st. Our live streaming for the Ideas Network will be off the air during these periods.

This absurdity, due to NBC’s broadcast rights deal with the IOC (International Olympic Committee), is yet another example of how the media has had its way with our politicians.
