On Election Night, cable giant Comcast Corp. will make it easier for subscribers to monitor campaign-related news on CNBC, CNN, C-SPAN, FOX, CNN Headline News, and MSNBC simultaneously. The company's recently launched news feed service, which is part of Comcast Central (channel 960), lets users toggle from one station to another on a single screen, eliminating the need to switch back and forth from different networks (I tried it out last week and now I'm addicted). Disclaimer: the service, which will continue after the election, isn’t available across Comcast’s entire footprint but is accessible to about 9 million customers that have digital cable.
