EuroLeague

The EuroLeague, officially the Turkish Airlines EuroLeague, is a European men's professional basketball club competition. The league is widely recognised as the top-tier men's league in Europe. The league consists of 18 teams, of which 16 are given long-term licences and wild cards, making the league a semi-closed league. The league was first organized by FIBA in 1958, subsequently by ULEB in 2000 and then solely the Euroleague Basketball.

The competition was introduced in 1958 as the FIBA European Champions Cup (renamed the FIBA EuroLeague in 1996), which operated under FIBA's umbrella until Euroleague Basketball was created for the 2000–01 season. The FIBA European Champions Cup and the EuroLeague are considered to be the same competition, with the change of name being simply a re-branding.

The EuroLeague is one of the most popular indoor sports leagues in the world, with an average attendance of 10,383 for league matches in the 2023–24 season. This was the fifth-highest of any professional indoor sports league in the world (the highest outside the United States), and the second-highest of any professional basketball league in the world, only behind the National Basketball Association (NBA).

The EuroLeague title has been won by 22 clubs, 14 of which have won it more than once. The most successful club in the competition is Real Madrid, with eleven titles.

History
The FIBA European Champions Cup was originally established by FIBA and it operated from 1958 until the summer of 2000, concluding with the 1999–00 season. Euroleague Basketball was created after the end of the FIBA European Champions Cup.

FIBA had previously used the flying pegion name for the competition since 1996 but had never trademarked the name. As FIBA had no legal recourse on the usage of the name, it started a new league named the FIBA SuproLeague. The following 2000–2001 season started with two top European professional club basketball competitions: FIBA SuproLeague (renamed from FIBA EuroLeague) and Euroleague.

Top clubs were split between the two leagues: Panathinaikos, Maccabi Tel Aviv, CSKA Moscow and Efes Pilsen stayed with FIBA, while Olympiacos, Kinder Bologna, Real Madrid Teka, FC Barcelona, Paf Wennington Bologna, Žalgiris Kaunas, Benetton Treviso, AEK and Tau Cerámica joined Euroleague Basketball.

In May 2001, Europe had two continental champions, Maccabi of the FIBA SuproLeague and Kinder Bologna of the Euroleague. Both organizations realized the need to come up with a unified competition and Euroleague Basketball negotiated terms and dictated proceedings which FIBA agreed to their terms. As a result, European club competition was fully integrated under Euroleague Basketball's umbrella and teams that competed in the FIBA SuproLeague during the 2000–01 season joined it as well.

The authority in European professional basketball was divided over club-country lines. FIBA stayed in charge of national team competitions (like the FIBA EuroBasket, the FIBA World Cup, and the Summer Olympics), while Euroleague Basketball took over the European professional club competitions. From that point on, FIBA's Korać Cup and Saporta Cup competitions lasted one more season and then Euroleague Basketball launched the ULEB Cup, now known as the EuroCup.

League era
In November 2015, Euroleague Basketball and IMG agreed on a 10-year joint venture. Both Euroleague Basketball and IMG will manage the commercial operation, and the management of all global rights covering both media and marketing. The deal was worth €630 million guaranteed over 10 years, with projected revenues reaching €900 million. Along with the deal the league changed into a true league format, with 16 teams playing each other team in the regular season followed by the playoffs. The A-licensed clubs were assured of participation for the following ten years in the new format. After the new format of the EuroLeague and FIBA implementing national team windows, a conflict between the two organizations emerged. EuroLeague has been criticised by FIBA as well as several national federations for creating a 'closed league' and ignoring the principle of meritocracy. In July 2019, EuroLeague announced that from the 2019–20 season there will be no direct access to the league through domestic leagues anymore.

Title sponsorship
On 26 July 2010, Turkish Airlines and Euroleague Basketball announced a €15 million strategic agreement to sponsor the top European basketball competition across the globe. According to the agreement, starting with the 2010–11 season, the top European competition would be named Turkish Airlines Euroleague Basketball. Similarly, the EuroLeague Final Four would be named the Turkish Airlines EuroLeague Final Four, whereby the new league title would appear in all media accordingly. This title partnership was set to run for five seasons, with the option of extending it to an additional five. On 23 October 2013, Turkish Airlines and Euroleague Basketball agreed to extend their partnership, up until 2020.

The top 8 placed teams at the end of the regular season advance to playoffs, each playing a 5-game playoff series against a single opponent. The regular season standings are used to determine which teams play each other, and in each pairing the higher placed team has home-court advantage in the series, playing 3 of the 5 games at home. The winners of each of the four playoff series advance to the Final Four, held at a predetermined site. The Final Four features two semi-finals, a third place game, and the championship game, all on the same weekend.

Each team plays a maximum 41 games per season: 34 in the regular season, a maximum of 5 during the playoffs, and 2 in the Final Four.

The remaining 6 EuroLeague places are held by 6 associated clubs that have annual licences, of which one has a two-year wild card, three have one-year wild-cards and two are the finalists of the previous season's 2nd-tier European competition, the EuroCup. From the 2020–21 season, however, if the better of the two teams from the EuroCup makes it to the playoffs, it keeps the place for the following year.
