Actually, newspapers follow the practice of using numerals for numbers less than ten, as recommended by the Associated Press Style Guide in the US, to save space. The Chicago Manual of Style recommends using words for numbers up to one hundred. Several other sites suggest that numerals should not be used whenever the number can be written out in words (obviously, this would mean that numerals should not be used up to one hundred, and also for other numbers such as three hundred or ten million).
