There are two main ways that people perform improv comedy. The first way is called shortform improv. This style uses quick games or structures. Often, a performer will ask the audience for a suggestion to start a scene. 
Improv has a very long history in Western theatre. The earliest records come from the Atellan Farce in 391 BC. Much later, from the 16th to the 18th centuries, performers in Italy used a style called commedia dell'arte. They would improvise based on a broad outline while performing in the streets. In the late 1800s, famous teachers like Konstantin Stanislavski used improv to train actors. In the 1940s, 50s, and 60s, Viola Spolin developed many specific techniques. She even wrote a book called Improvisation For The Theater to teach these skills.
Many famous comedy groups and stars grew from these ideas. In Chicago, Paul Sills and David Shepherd started The Compass Players. This group later led to the famous troupe called The Second City. 
Today, the skills used in improv are used in many different places. It is not just for the stage or for movies. Some people use it in classrooms as a way to help students learn. In businesses, it is used to help people work better in teams. It can also help people improve how they communicate with others. Even doctors or therapists sometimes use it to help people understand their own feelings. It is a tool that helps people solve problems in creative ways.
Improvisational theatre, often called improv or impro, is a unique form of performance. In this style, most or all of the show is unplanned. Performers do not use a written script. Instead, they create dialogue, action, and characters spontaneously. This happens in real time through collaboration between the players. 
Modern improvisational comedy generally falls into two categories: shortform and longform. Shortform improv consists of short scenes. These are usually built from a predetermined game or structure. A performer might use an audience suggestion to start the scene. One example is a game where a director points to an actor. That actor must then rewind and say a new line. 
Improvisation has a deep history in Western culture. The earliest documented use is found in the Atellan Farce of 391 BC. From the 16th to the 18th centuries, Italian performers practiced commedia dell'arte. They improvised based on broad outlines in the streets. In the 1890s, theorists like Konstantin Stanislavski used improvisation for actor training. In the 1940s, 50s, and 60s, Viola Spolin developed specific techniques. She wrote the book Improvisation For The Theater to teach these methods. 
Chicago became a major center for the modern improv movement. Paul Sills and David Shepherd started The Compass Players. This group eventually led to the creation of The Second City. 
Other organizations have helped improv grow globally. Dick Chudnow founded ComedySportz in Milwaukee in 1984. This organization expanded to include ComedySportz-Madison in 1985. The first Comedy League of America National Tournament was held in 1988. It featured 10 participating teams. Today, CSz Worldwide includes 29 international cities. In London, Keith Johnstone created Theatresports. This format inspired the popular television show Whose Line Is It Anyway? Improv is now popular in many places, including the United Kingdom and Asia.
Beyond the stage, improv skills are used in many other fields. This practice is known as applied improvisation. In classrooms, it serves as an educational tool. In businesses, it helps people develop communication and teamwork skills. It is also used in psychotherapy. Therapists use it to help people gain insight into their feelings and relationships. Even in film and television, improv helps actors develop characters and scripts.
Improvisation also reaches into experimental and political art. Groups like The Open Theater explored social issues through improvisation. In Poland, Jerzy Grotowski developed "poor theatre" using similar processes. Some performances are even interactive and hyperreal. For example, the play 66 Minutes in Damascus uses a sensory environment. The audience plays the role of kidnapped tourists. There is even a digital version called netprov. This uses social media to create fictional scenarios in real-time.
