Under Mel, CBS/Infinity had a policy against streaming. CBS began streaming their NT stations in later 2003 and 2004, but WSJS was not included in the deal. Started as an oversight at the corporate VP level, then once they decided to sell the market, they weren't about to invest in the hardware.
The original WSJS streaming was done by Broadcast.com (later Yahoo Broadcast) on a barter deal. Honestly, it was one of the sweetest barter deals around. Five units a week, they provided the computer, software, broadband internet connection and router!
Actual streaming was done in Texas. Signal was sent from station to central distribution point. The number of streams available were determined by the demand.
