Giants win over Tigers doesn't score for Fox in viewer numbers The Detroit Tigers aren't the only ones having trouble scoring in the World Series. Just 12.3 million people tuned into Fox to watch Game 2 of the World Series, which saw the San Francisco Giants take a two games to none lead over Detroit with a 2-0 win. In Game 1, 12.2 million people watched the game. If the numbers don't improve, this could end up being the least-watched Fall Classic on record. Game 3 of the best of seven series is in Detroit on Saturday. For Fox, the longer the series the better. Fan interest could pick up if the Tigers make a comeback and additional games mean more revenue. According to Nielsen, the least watched World Series was in 2008 when the Philadelphia Phillies beat the Tampa Bay Rays in five games. The average audience that year was 13.6 million. The 2010 series between the Giants and Rangers was the second-least watched in the books with 14.3 million viewers per game. While Detroit and San Francisco have loyal fans, neither team has a national following like the New York Yankees or Boston Red Sox. Since 2000, only three World Series have averaged more than 20 million viewers per game and all involved either the Yankees or Red Sox. Overall though, viewership for the World Series has been on a downward trend for two decades. From 1973, when Nielsen started measuring viewing numbers, through 1992, the World Series routinely drew more than 30 million viewers and even cracked the 40 million mark a few times. Game one blowout is bad news for Fox
