[2] The first Next Generation Tournament Final Four was held in 2003, in Barcelona, Spain.

Its sponsorship name was originally the Nike International Junior Tournament (NIJT).

The four regional tournaments were originally the Torneo Città di Roma, the Torneig de Bàsquet Junior Ciutat de L'Hospitalet, the Kaunas International Junior Tournament, and the Belgrade International Junior Tournament.

[3] In addition to the 4 winners of each of the regional qualification tournaments, the reigning champion from the previous season, as well as three wild card invitees, also take part in the Final Tournament, which is played by eight teams that are divided into two groups of four teams each.

The two group winners play on the same court where the senior men's EuroLeague Final Four is held.
