I've been waylaid for much of today by problems with a virus in my office computer, so apologies for the lack of posts today.

But Nielsen has begun reporting TV ratings reports again after a power outage in Oldsmar during the wee hours Wednesday morning disrupted data collection efforts. Some local data was made available to clients last night, while national ratings were rolled out today, according to spokesman Gary Holmes.

There's still no word on why a transformer blew out at about 2 a.m. Wednesday, but the failure sent a power surge through Nielsen's systems which required them to restart much of their equipment over the day Wednesday, Holmes said. The disruption left clients without ratings for the better part of a day and revealed that their backup power systems might not be enough to halt disruptions in TV ratings during an emergency.
