Because it indicates that the speaker does not pronounce it differently than without the apostrophe.
Once a word is already plural and ends in /z/, we don’t add another /z/ to make it possessive. It sounds exactly the same.
But we do add an apostrophe in writing so that people know what we meant, for goodness’ sake. :)
Both ways are correct ways to write it: New York Times' and New York Times's. How you personally write it depends on how you say it. If you say "Timz" when making it possessive, you simply add an apostrophe after the S (Times'), but if you say Timziz" when making it possessive, you add and apostrophe S (Times's).
The New York Times being a media outlet, they have what is called a style guide. In their style guide, they have prescribed how possessive of New York Times should appear. Based on what I've seen, the New York Times itself only publishes using an apostrophe without an additional S. That, however, doesn't make writing New York Times's wrong, just wrong if you work for the New York Times.
The only names that have a hard and fast rule about how to make them possessive with an apostrophe and no additional S are Biblical names (e.g., Jesus' and Moses').
