An average of over 19 million U.S. viewers watched the six games of this year’s World Series between the Philadelphia Phillies and the New York Yankees, the most since an average of 25.4 million people saw the Red Sox sweep the Cardinals in 2004. Game 4 of the series was also the most watched single World Series game (22.5 million viewers) since 2004.

A legendary 6-RBI game by Hideki Matsui in Game 6 propelled the Yankee DH from a postseason afterthought to World Series MVP. The series-clinching performance resounded throughout the internet as Matsui’s buzz soared across blogs and message boards in the hours after the final out:

Of all the players participating in the World Series, Alex Rodriguez delivered the most buzz. As A-Rod marched through October on his quest toward his first championship ring, his internet buzz was at a level three times higher than any other Yankee or Phillie. Surprisingly, the next-closest player in terms of buzz during the postseason was pitcher A.J. Burnett, who saw his share of ups and downs throughout the playoffs. Derek Jeter’s on-field steadiness translated to the blogosphere with the third-highest buzz of any World Series participant. The most buzzed-about Phillie was second baseman Chase Utley, whose five-homerun performance in the Fall Classic had many wondering if he could take MVP honors back to the losing city.

FOX, which aired live coverage of Game 5 of Major League Baseball’s National League Championship Series — instead of the debate, rounded out the top three.

CBS’s post-debate analysis also made the top ten.

Overall, NBC won the night with an average audience of almost 8 million viewers, while FOX took second place with almost 7.8 million average viewers. CBS and ABC claimed third and fourth places with roughly 7.4 million and 7 million average viewers, respectively. Univision and the CW followed in fifth and sixth places with average audiences of roughly 2.8 million and 2.4 million viewers, respectively.

CBS dominated the rest of Nielsen’s top 10 list, with “Two And Half Men,” “CSI: Miami,” “Worst Week,” “The Big Bang Theory,” and “How I Met Your Mother” claiming five of the nine remaining slots.

Overall, ABC won the night with an average audience of just over 13.5 million viewers, while CBS took second place with almost 11.6 million average viewers. FOX and NBC claimed third and fourth places with roughly 7.42 million and 7.39 million average viewers, respectively. Univision and the CW followed in fifth and sixth places with average audiences of roughly 4.2 million and 3.4 million viewers, respectively.

Manny Boosts Dodgers…TV Ratings?
What are the odds that the Los Angeles Dodgers would have made it to the MLB National League Championship Series without Manny Ramirez?  Since Manny’s move west to join the Dodgers, the team has gone from one game under .500 to seven games above. 

Local L.A. fans’ interest in the Dodgers is also on the rise.  Ramirez’s first game with the Dodgers drew 5.2% of all TV households in the L.A. market – the team’s largest TV audience of the season.  Overall, local ratings for Dodgers games are up by 35% since August 1.

Rays’ First Post-Season Triggers TV Ratings Surge
The Red Sox, Ramirez’s former team, didn’t miss a beat after losing their all-star slugger to the Dodgers.  The resurgent Tampa Bay Rays, however, may change that. 

The Rays, who are competing in their first post-season in franchise history, are drawing strong TV audiences in their local Tampa Bay market, with ratings up by 97% over last season, to date.  When the Rays and the Red Sox last faced off on July 2, 9% of all households in the Tampa Bay market tuned in for the game, setting a Rays franchise ratings record.

Historically, at least where league championship series are involved, ratings have been significantly higher when teams from major markets, such as Chicago, Boston and Los Angeles, are involved. A breakdown of those matchups will be featured prior to the upcoming NL and AL championship series.

Below are historical ratings since 2000 for Division Series Playoffs. Numbers from 2007 division games broadcast on TNT and TBS are combined average viewership for both National and American leagues. The 13 games broadcast on TBS drew an average of 5.7 million viewers, while the four games picked up by TNT drew an average of 1.6 million viewers.
