Currently the guide asks customers to find a category and remember a category number or channel number to bring up a desired program. My suggestion is that the guide should have a keyword search feature ( using one channel) where on entering a keyword there would be a display of channels subscribed to and others that customers might wish to subscribe to (sales function) . Then if you keyed in hockey the hockey broadcasts for that day would be displayed with channel numbers. Or if you keyed in Seattle; the Seattle stations and channel numbers would be displayed.
This need not be a terribly complex function. I always forget the number and category of Public Television; for example.
