According to an article today from Reuters, the NHL's television reach and broadcast rights fees in the U.S. lag behind those of the other three major sports (NFL, NBA, and MLB), but they do appear to be growing strongly. In particular, there is a question as to whether the growth of league-owned networks (NFL Network, NHL Network, etc.) might eventually have an impact on the fees that leagues earn from the broadcasters:

League	Broadcast partners	Annual value of deals
NFL	Fox, NBC, CBS, DirecTV	nearly $4.1 billion
NBA	TNT, ESPN, ABC	$937.5 million
MLB	TBS, Fox, ESPN, DirecTV, numerous cable
	operators, XM Radio	$900 million
NHL	Versus, NBC	over $72.5 million

For the NHL, that $72.5 million comes from the Versus contract, and then in addition to that you have advertising revenues split with NBC (there's no up-front fee as with the other leagues).

As to the overall audience that the different broadcasters can reach, we have the following:

Networks	Households
Broadcasters (ABC, CBS, Fox and NBC)	114.5 million
TBS	99.1 million
TNT	98.2 million
ESPN	98.1 million
Versus	75.1 million

Versus has come a long way, but there is still a significant gap relative to the rest of the pack, both in terms of households reached as well as visibility.

The interesting angle, to me, that bears watching over the next few years is the growth of the NHL Network - which, as anyone who has it knows, is Pure Chewing Satisfaction to a hardcore hockey fan. 

Network	Subscribers	League games aired	Established
MLB Network	52 million	over 52	2009
NFL Network	45 million+	8	2003
NBA TV	18 million	96	1999
NHL Network	12-15 million	75	2007

Note: NBA TV is on target to expand distribution to 37 million subscribers by the start of next season this fall, while the NHL Network, established first in Canada in 2001, is on track for 30 million subscribers.

The question that Reuters raises here is whether the growth of league-owned networks will threaten the big broadcast fees enjoyed by the NFL, NBA, and MLB. For the NHL, those fees are relatively minor, and instead, this situation represents a growth opportunity via the NHL Network and Versus.
