When did NBA start using Wilson?

The NBA started using Wilson as the official basketball manufacturer during the 2021-2022 season. Before that, they used Spalding for many years. Similar to how different brands make different kinds of shoes, different companies make different kinds of basketballs. Just like how they switched from Spalding to Wilson, the NBA has changed basketball brands in the past too. For example, in the 1940s, they used a brand called Mikasa. But now, the NBA has chosen Wilson as their official basketball supplier.
