CMCSA - Get Report) made when it, the original owner of Versus, acquired a majority interest in NBC Universal. Television isn't the only area where ESPN might be vulnerable. However, it is more important than radio, which could take a hit. Just the other day CBS ( CBS - Get Report) and Cumulus Media ( CMLS - Get Report) struck a deal to partner on CBS Sports Radio. Even though the arrangement takes place in the relatively obscure confines of the radio business, it carries somewhat meaningful, albeit limited, implications. First, in some markets, CBS and Cumulus radio stations might be able to share talent. For example, one of the nation's biggest all-sports radio stations, New York City's WFAN, could simulcast some of its programming -- the Boomer Esiason and Craig Carton morning show, or Mike Francesa's afternoon show, for example -- not only on CBS radio stations across the country, but Cumulus stations as well. Second, and maybe most important, upon signing the deal with CBS Cumulus nixed its sales and marketing agreements with ESPN and will not renew distribution deals that put ESPN Radio programming on Cumulus stations. Initially CBS Sports Radio will reach fewer than half of the 24 million listeners who hear ESPN Radio. But given the relationship and competitive landscape, this could change. That's really the key, getting ears to make the switch from ESPN Radio to CBS Sports Radio. Given the relatively miniscule impact radio has on the bottom lines at Disney and CBS, this likely will not come close to changing the game. In fact, I would go so far as to say that ESPN Radio could shut down tomorrow and investors might not even notice. DIS would trade, by and large, unaffected by the noise. If CBS can ding ESPN in radio, imagine the damage NBC might be able to do in the more important area of TV. Comcast's NBC Sports Network, now a fully functional part of the NBC Sports family, could put a hurt on ESPN, and by extension Disney. A few points to consider. Business is strong at ESPN. On Disney's most recent quarterly earnings report (Transcript via Seeking Alpha), the company touted ESPN as the most-watched 24-hour cable network among 18 to 49 year olds in 2011. Advertising revenue continues to grow at ESPN, up 14% in the second quarter, year over year, and trending up in the high single digits for the current quarter. These numbers not only speak to ESPN's success, but the market opportunity that exists for premium sports coverage. It's the one area where TV as we have historically known it -- as key appointment viewing -- still reigns supreme.
Comcast cable customers have access to the WatchESPN app. That extends ESPN's mobile reach to 40 million, according to data released on the above-cited call. Comcast must play a balancing act between giving its subscribers what they want (access to properties such as ESPN across devices) and promoting their own competitive offerings. Content. That's what it comes down to. NBC Sports airs plenty of solid programming, ranging from the National Football League to PGA Golf to the current cornerstones of the NBC Sports Network, the National Hockey League and the Tour de France. Both networks will cover the Summer Olympics, with sister stations, MSNBC and CNBC, likely picking up some events, just as CNBC did during this past season's NHL playoffs. In terms of content, however, ESPN still dominates. Not only does it broadcast all major sports -- on a much more consistent and frequent basis than NBC -- it owns the image of the go-to network for sports programming. The only way NBC, and the NBC Sports Network in particular, can chip away at this is to make a stand for the content that allows ESPN to build the brand -- that means major events and the ongoing coverage that brings eyeballs night after night, such as Major League Baseball and NBA broadcasts. In terms of penetration, NBC Sports Network is actually not all that far behind ESPN. According to Comcast and Disney's most recent annual reports, ESPN counts about 99 million subscribers, while NBC Sports Network boasts 76 million. By comparison, ESPN 2 reaches 99 million subscribers, ESPN News (73 million), CNBC (97 million), MSNBC (95 million) and Comcast's Golf Channel (85 million). To most effectively compete for content, NBC Sports Network needs to sport a larger subscriber number. At the same time, it can always leverage its ability to run programming on NBC as well as its other powerful cable networks. Endpoint: As I continue to argue, premium content is what makes media stocks strong buys. I love Disney as well as Comcast. Sports remain the end-all and be-all of premium content. If Comcast can chip away at ESPN and similar media stalwarts, it might just replace Disney as the sports and entertainment leader of the new century.
