Although it had been 108 years since the Chicago Cubs won a World Series, they were involved in 7 World Series between those dates all of which they lost.

1910, 1918, 1929, 1932, 1935, 1938, and 1945.

If Harry Caray was alive today, I'm sure his first comment would be "CUBBIES WIN" The curse has been broken.

The Cubs did win back to back World Series in 1907 and 1908, although never sweeping a Series. In 1908 they won it in 5 games.

Another interesting note is the attendance difference, the last game of the 1908 series saw just 6,210 people compared to 38,091 this year and was seen on television by nearly 40 million, a new record.
