Since the league's inaugural season, a total of four clubs have been crowned as the Champions: ATK (3), Chennaiyin (2), Bengaluru (1) and Mumbai City (1). The league winners participates directly in the AFC Champions League and the ISL Final winner participates in the AFC Cup qualifying-playoffs. However, before the 2017–18 season, the league expanded to ten teams, expanded its schedule to six months, and earned recognition from the AFC. Each season lasted just 3 months, from October to December, and matches were held daily. The competition was also structured along the same lines as the Indian Premier League, the country's premier Twenty20 franchise-based cricket competition. During its first three seasons, the competition operated without official recognition from the Asian Football Confederation (AFC), the governing body for the sport in Asia. The league began in October 2014 with eight teams. The competition was founded on 21 October 2013 with the goal of growing the sport of football in India and increasing its exposure in the country. The season then culminates with the ISL Final to determine the Champions who are presented with the ISL Trophy.

At the end of the league stage, the team with the most points gets declared the Premiers and presented with a trophy named League Winners Shield, and the top four clubs qualify for the play-offs. During the league stage of the competition, each club plays against all the other clubs in a round-robin style. Each season of the tournament generally runs from November to March. For sponsorship ties with Hero MotoCorp, it is officially called Hero Indian Super League. It is organised by All India Football Federation and their commercial partners Football Sports Development Limited.

The Indian Super League ( ISL) is a men's professional football league, which is the highest level league in Indian football system.
