Because Nike Sells its products in 160 of the 196 countries. However a list of these (or the 36 not sold to) has not been located. As such they are not listed on the map. Also to note, only countries where more then 1000 people are employed are listed. While Nike has a list of all there shops. It is 4 pages long, and would make the map to cluttered to have lines going to each.
