Euroleague interest remains heavily concentrated in a few countries that form the core of its fan base. Lithuania sits at the top, followed by Serbia, Greece, Montenegro, and Bosnia and Herzegovina. These countries consistently generate the strongest search activity and engagement for the league.

According to Google Trends data, interest follows a clear seasonal pattern: it rises during the Euroleague season from October to May and drops in the summer. This cycle has remained steady over the past five years.

Within the leading countries, the attention is even more focused in specific regions. In Lithuania, Kaunas County shows the highest engagement, ahead of Alytus and Vilnius. In Greece, interest is strongest around Athens, with areas such as Penteli, Dionysos, Zografou, and Nea Erythraia showing the most activity. In Serbia, Vojvodina ranks highest.

These results underline a concentrated fan base in Southern and Eastern Europe, where Euroleague holds its strongest cultural and sporting presence.
