The US is planning a major auction of broadcast bandwidth, which could mean a bonanza for public broadcasting. “The auction, now scheduled for 2009, is being made possible by the switch from analog to digital broadcasting technology. Digital broadcasting requires less bandwidth than analog, meaning parts of the spectrum can be freed up for sale to cell phone companies, wireless Internet firms and others.the auction could generate anywhere from $500 million to $5 billion that could be used to set up a permanent trust fund for public broadcasting.”
