MLB.com has a plan set up that for $14.95, you can listen to any major league game live through the Web - for any team - all season long. So, when I'm traveling, whether I'm in Los Angeles, Phoenix, Orlando, Chicago, Boston, New York or Seattle, I can take one of the home comforts with me.
On the flip side, we don't have TV access. MLB TV simply doesn't cater well to fans who live near their team. Foolishly, MLB TV will let me watch every team except for those near me, assuming it's probably on somewhere I can see it. Wrong. Stupidly wrong. So, instead of paying $79.95 a year, I get better service for $14.95, and don't ask for video. But that's a different issue. Baseball is one of the few games that really lends itself well for radio, and MLB.com does it very well and at a good price.
