The idea of starting Koffee with Karan came to Karan Johar at a time when the style of celebrity interviews was quite formal. Karan wanted the way of interacting with the stars to be a little different and the audience should get to see a new aspect of their personality. His idea was to make two film stars sit together and ask them interesting questions related to friendship, relationships and film career. In this way, along with entertainment, the audience could get a chance to know such stories from the life of the stars which are not usually revealed.
It is said that in June 2004, Karan had presented the idea of this show to his father and famous filmmaker Yash Johar. Initially his father was not very excited about this proposal. He had humorously asked that when Karan already talks to his friends then why would anyone pay money for the same conversation. Despite this, Karan continued working on his idea. Meanwhile, Yash Johar died on 26 June 2004. Even amidst the grief of losing his father, Karan decided to fulfill his dream.
Karan started shooting for the show on 16 August 2004 and its first episode aired on Star World India on 19 November 2004. Shahrukh Khan and Kajol had arrived as guests in the first episode. The friendship and frank conversation between the two gave a special start to the show. After this the rapid fire round became the identity of the show. During this period, stars were asked frequent questions and their answers were often entertaining and also became the cause of discussion and controversy.
Late actress Sridevi also never came as a guest on this show. Karan Johar has been his fan but it was not possible for him to attend the show. Similarly, actors Irrfan Khan and Nawazuddin Siddiqui were also not seen in the program. Regarding film producer Aditya Chopra, Karan Johar has also said that he did not have the courage to invite him to the show. Late actor Sushant Singh Rajput also did not become a part of the show. However, there was not the same reason behind all these artists not coming to the show and it would not be right to reach any conclusion in every case without personal reasons or official confirmation.
