The World Series matchup is set. It's the San Francisco Giants (Go Giants!) vs. the Texas Rangers. Here's your chance to guess the average viewership** for the Series.
Since the longer the series goes, the higher the viewership and ratings rise, to keep the guessing comparable, make your average viewership guess assuming a 5 game Series (the average Series length in the last 10 years was 5.3 games).
That being the case, I like a 5 game series to average 16 million viewers, about the same as the 2006 series.

*While there were six telecasts for the 2008 series, there were only five games. The sixth telecast was the completion of game five which was suspended due to rain.
**Of course average viewership means nothing to advertising revenue, but like most historical ratings data, we lack historical demo group ratings for comparison. The 2009 series averaged a 6.2 adults 18-49 rating, while the 2008 series averaged just a 4.4 rating.
