I suggested to FNC awhile ago that I'd love to see a 24/7 LIVE version of the Fox News Channel, sort of like CNN's Headline News (in addition to the current FNC). I love the second chance to catch O'Reilly at 11pm ET, Brit at midnight, etc., but find myself switching to Headline News, MSNBC, etc. often when news breaks after 11pm.
Channels for business (like CNBC) and entertainment news could work well also, IMHO.
