A few years back, Major League Baseball demanded that all MLB baseball teams hand over their websites to the league as part of their effort to create MLB Advanced Media, a division devoted to managing the online presence of Major League Baseball. While MLB may go way overboard in claiming control over certain content, its online efforts have been quite a success. There was a rumored (and later scrapped) IPO plan -- but the company is apparently still doing amazingly well, with talk of it being valued somewhere around $5 billion. Already, MLBAM has tried to expand its coverage by running websites for other sports and even musicians.

All of that success apparently caught the attention of the National Hockey League, who had apparently let teams run their own damn sites for a while. However, it recently decided to bring them all in house -- but teams aren't thrilled with the idea. In fact, the NY Rangers are now suing the NHL for antitrust violations in trying to take over their site. The Rangers claim that the site is an important part of their team's marketing efforts and it acts as a competitive differentiator. They're also not happy that they've spent all this time building up traffic only to turn it over to the NHL. There are a few important differences with the NHL's plan compared to the MLB's. First, MLB took over all team sites years ago, before web sites were so important. These days, most teams recognize how valuable those sites are and have already built up a ton of traffic. Much more importantly, Major League Baseball has a special antitrust exemption that no other sports have. So, even if a baseball team had wanted to charge MLB with antitrust violations, it would have been difficult given the exemption. Since the NHL doesn't have that exemption, it's going to have to put up a fight to get the Rangers to hand over their website.
