The Yankees have proven to be just as strong of a brand in the social media space as they are in other forms of league marketing. Over the course of Spring Training, the Yankees averaged 6,566 new Facebook fans every day, well above the league average of 1,098 daily adds. They also led all teams in overall Facebook fans by a large margin, with 3,398,116 at the end of Spring Training. The Red Sox and Cubs are the only other franchises to top the 1 million fan mark. The D'Backs saw the biggest increase in Facebook followers after Spring Training, with a 16.4% jump. The following chart lists MLB teams by number of Facebook followers (THE DAILY).

FAN FINDINGS: In San Jose, Mike Swift notes Facebook has taken an "unprecedented look at the millions of members around the world who have hit the 'Like' button" for their favorite MLB team, "or who posted updates about their feelings about their team after a win or a loss." The site also has "developed a 'fair weather fan' index for fans who only follow their team when it is winning." According to Facebook's findings, "nearly 50 percent of fans of the Cardinals and the Minnesota Twins are women, while just more than a quarter" of Blue Jays fans were female. The Yankees and Red Sox "have the most extensive 'fan Diaspora,' as measured by the median distance their fans live from Yankee Stadium or Fenway Park." A's fans were the "only fan community to average more than 500 friends on Facebook," while fans of the Angels and the Dodgers "have the fewest friends on Facebook, averaging 350 or less." Phillies fans "were least likely to hit the 'Like' button for any other team" (SAN JOSE MERCURY NEWS, 3/31).
