It's been a long, long while since we've heard any good news on the HD expansion front from Lexington-based Insight Communications
, but at long last, the carrier has emerged from the woodwork to assure us all that it's still alive and well. The firm has just announced its intentions to carry 56 high-definition channels by "early December," with a few of the newcomers to include FOX News HD, CNN HD, The History Channel HD and SciFi HD. A spokeswoman for the company admitted that most of the additions would be available at no cost, though we assume a few of 'em may fall into pay tiers. Hang tight, Insight users -- help is on the way.
