Broadcast, cable, and satellite video services are adopting IT-centric models for signal management, a trend that began year ago with the first streaming video services.

This is likely the only house in my neighborhood which has both cable TV service and a bevy of roof-top and attic antennas, a combination that didn’t make sense to my neighbors until Hurricane Sandy blew ashore in 2012 and the high winds it generated took down a 75’-tall oak tree nearb..Read more
