When you fold the newspaper its area is halved each time. At the same time the pile's thickness is doubled and grows rapidly.

So after the first seven folds a pile has its area very small (only 1/128) of the full sheet's area, and its thickness is 128 times more. So it's a very hard task to fold so small and so thick pile for the eighth time, and almost impossible to do the ninth fold.
