Have commas been cut from the budget?

Growing up and up to this point in my writing career, I've always learned (and practiced!) that when writing a numeral, if it is longer than four digits, a comma is inserted after the third (or after every third) digit. For example: 1,000; 27,500; 100,000,000.
Lately, however, I have noticed more and more four-digit numbers written without the comma. For example: 1000; $2500. I do not see the trend continuing with numbers more than four digits.
Is it now the rule or widely practiced/accepted that commas are not needed/used in four-digit numbers?
On a side note, if this has changed, I wonder how when, and by whom such changes are decided/made? And how is one who is not currently a student or otherwise enrolled in grammar classes suppose to know? I must have missed out on a memo or secret sign in the sky.
Thanks in advance for any help you can offer regarding commas with numbers.
