The black linings on a basketball are called the seams.
An American football typically has 4 seams – one on each side where the two pieces of leather that make up the football are stitched together.
The first basketball was invented in 1942 by a physical education teacher named, James Naismith. The first basketball had seams on the outside that was used to identify the type of ball it was, and it was also used to for support. The seams in the basketball help the person playing keep grip of the ball.
