First season
The inaugural season of the tournament started on 18 April 2008 and lasted for 46 days with 59 matches scheduled, out of which 58 took place and 1 was washed out due to rain. The final was played in DY Patil Stadium, Nerul, Navi Mumbai. Every team played each other both at home and away in a round robin system. The top four ranking sides progressed to the knockout stage of semi-finals followed by a final. Rajasthan Royals defeated Chennai Super Kings in a last ball thriller and emerged as the inaugural IPL champions.
Second season
The 2009 season coincided with the general elections in India. Owing to concerns regarding players' security, the venue was shifted to South Africa. The format of the tournament remained same as the inaugural one. Deccan Chargers, who finished last in the first season, came out as eventual winners defeating the Royal Challengers Bangalore in the final.
Third season
The third season opened in January 2010 with the auction for players. 66 players were on offer but only 11 players were sold. In this season, Deccan Chargers did not play at their preferred home location of Hyderabad, India due to the ongoing political crisis in the Telangana region . The new bases for the champions this season were Nagpur, Navi Mumbai and Cuttack. Four teams qualified for the semi-finals. The first semi-final was won by Mumbai Indians who defeated Bangalore Royal Challengers by 35 runs. Chennai Super Kings defeated Deccan Chargers in the second semi-final. The final was played between Chennai Super Kings and Mumbai Indians. Chennai Super Kings won by a margin of 22 runs.
Fourth season
On 21 March 2010, it was announced in Chennai that two new teams from Pune and Kochi will be added to the IPL for the fourth season. However, the bid around the Kochi franchisee turned controversial resulting in the resignation of minister, Shashi Tharoor from the Central Government and investigations by various departments of the Government of India into the financial dealings of IPL and the other existing franchisees. Later, Lalit Modi was also removed from IPL chairmanship by BCCI. On 5 December 2010, it was confirmed that Kochi will take part in the fourth season of IPL.
In October 2010, the Rajasthan Royals and Kings XI Punjab had their franchises terminated for breaching ownership rules. The new Kochi franchise was also issued a warning to resolve all their ownership disputes.
The addition of teams representing Pune and Kochi was to have increased the number of franchises from 8 to 10. The BCCI originally considered extending the tournament format used in previous season to ten teams, which would increase the number of matches from 60 to 94. Instead, the round-robin stage of the tournament was to have been replaced by a group stage with two groups of five, limiting the number of matches to 74.
In December 2010, it was announced that Kings XI Punjab and Rajasthan Royals would take part in the 2011 edition of the IPL per court order.
