Ever wonder why NBC broadcasts hockey?

Like arena football, the NHL is a time filler. It costs the General Electric Co. (NYSE: GE) network next to nothing to produce so any ratings benefits it gets are gravy, That's why NBC has to be happy the New York Rangers squared their best-of-seven Eastern Conference semifinal series against Buffalo on Tuesday night at Madison Square Garden. That guarantees a Game Six back in New York on Sunday afternoon following Friday night's fifth game in Buffalo.

And since one team will have a chance to clinch and advance to the Eastern Conference Finals against the New Jersey Devils or Ottawa Senators, ratings presumably will rise. The network can hope the game does better than Game Three, which drew a 1.8 Nielsen rating in New York, compared with a 2.1 for Fox's coverage of the NASCAR Nextel Cup Aaron's 499 and a 1.9 on CBS for its broadcast of the PGA Tour Byron Nelson Classic.

Those ratings are decidedly better than comparable NHL playoff games a year ago, but the fact that hockey trails every other major sport is worrisome.

The game does very well in regional markets such as Detroit, Buffalo, Pittsburgh and Minneapolis/St. Paul, but the days of drawing ratings comparable to baseball, basketfall and football are in the distant past. It hasn't helped that the NHL had a falling out with Walt Disney Co.'s (NYSE: DIS) ESPN following the lockout-lost 2004-05 season and chose Comcast Corp's (NASDAQ: CMCSA) VS network (formerly the Outdoor Life Network) as its cable home. The price tag: $67.5 million per year for two years versus $120 million per year for the previous five seasons on ESPN. Last year's average playoff rating on VS: a paltry 0.3%.

What can the NHL hope for June 2007? That the top U.S. media market has a team in the Finals for the first time since 1994.
