Subscribers to Comcast cable television in Palo Alto and neighboring cities have lost CSPAN2 from their channel offerings, unless they have digital cable service.
Comcast recently moved CSPAN2, which offers live coverage of congressional hearings and the U.S. Senate, to digital service.
It's not the first change in store for cable subscribers.
By early 2009, cable subscribers will need either a digital TV or a digital converter box to watch cable TV because of federal regulations, said Melissa Cavallo, Palo Alto's cable coordinator.
The City of Palo Alto controls the cable TV franchise for cable subscribers in Palo Alto, Menlo Park, East Palo Alto, Atherton and in faculty housing at Stanford University.
But the city has no control over which channels are offered to subscribers, other than the requirement of public access channels for government meetings and other local programming, Cavallo said.
