Twenty20 (T20) cricket

Rules and match structure

A T20 match consists of two innings, one per team, with each innings capped at 20 overs (an over = six legal deliveries) as noted in standard descriptions of overs. Bowlers are restricted in how many overs they may deliver—currently a maximum of four per bowler—and matches use fielding restriction periods (powerplays) to encourage aggressive batting early on. If scores finish level, a tie is usually resolved by a "super over": a one-over-per-side shootout to determine a winner.

Characteristics and tactics

T20 emphasizes high scoring, quick scoring rates and inventive shot-making. Teams favour aggressive openers, specialist finishers and bowlers skilled in variations (slower balls, yorkers, cutters). Fielding standards are also elevated, with boundary-saving dives and athletic catches becoming decisive. The compressed format forces different selection and captaincy decisions than in longer forms such as Test cricket.

History and development

The format began as a domestic experiment in England in 2003 to boost attendance and viewership. It rapidly spread worldwide and was adopted by the International Cricket Council for international competition. The first global tournament, the ICC T20 World Cup, was held in 2007; India won the inaugural edition. Since then the World Cup has continued at regular intervals and has been won by several different nations, reflecting the format's competitive balance and global reach (T20 World Cup).

Domestic leagues and commercial impact

T20's biggest commercial influence is its domestic franchise leagues. The Indian Premier League (IPL), launched in 2008, is the most prominent example, generating high revenues, attracting international stars, and influencing the format's tactics and broadcasting style. Other notable competitions include Australia's Big Bash League (BBL), the Caribbean Premier League (CPL), Pakistan Super League (PSL) and several national championships that have professionalized the shorter game and created global player markets.

Importance and notable distinctions

T20 has broadened cricket's audience by offering a time-limited, entertainment-focused experience that compares more directly to other mainstream sports in duration. It has driven rule innovations, technological aids (for broadcasting and officiating), and new career pathways for specialist players. At the same time, administrators and purists continue to balance T20's appeal with the preservation of longer formats—Test and One Day International cricket—so the sport retains its varied traditions and skills across formats.
