We all grumbled about NBC’s announcement that 5 p.m. on a Sunday afternoon (today) had been their chosen time to broadcast the documentary about Barbaro.

Newspapers and NBC media outlets dutifully had backup features today to feed into the broadcast.

So why is my television blasting out an NHL hockey game?

NBC Sports was caught in a broadcast mess today and Barbaro’s documentary was pulled. According to the hockey announcer, it is re-scheduled to be broadcast on Friday night at 9 p.m., with a re-broadcast at midnight.

The only problem is that it will only be shown on NBC’s cable network, CNBC. Barbaro fans without cable service (that includes me) will have to invite themselves to a friend’s house…or call the cable guy, pronto.
