Just a couple of weeks back, Facebook entered into an agreement with Warner Brothers to rent "The Dark Knight" for 48-hour stints. But, according to Business Insider, "Live sports actually makes more sense than movie rentals -- users are more likely to share a live event with a real-time status update like 'check this amazing game out.'" At the moment, MLB swears it's only working with Facebook to figure out who's interested in watching and sharing games online in order to promote MLB.TV more effectively.
