Nowadays in Tamil cinema, there is a big need to do some grand and tireless promotional activities to advertise the film to the fans. In addition, the producers are organising audio launch events on a magnum opus scale to attract fans.

But the music release function of a film was not such a big event in the old times. If the movie succeeds, it will be followed by events such as silver jubilee and golden jubilee celebrations. Thiagarajan, actor, director and Prashanth's father, was the one who started the grand audio launch trend in those times.

Thiagarajan was a close friend to the legendary actor and Tamil Nadu's former Chief Minister MGR. Thiagarajan started his career as a boxer and unexpectedly became an actor. At that time, MGR advised him to be a full-time actor as he entered the cinema. Accepting this, Thiagarajan also quit boxing and became a complete actor.

Thiagarajan directed, produced and starred in the film 'Poovukkul Boogambam' in 1988. The movie's soundtrack was composed by Sangeetharajan. Thiagarajan met MGR after completing the works and requested him to release the songs for the film as the chief guest. MGR agreed immediately without any objection.

While the whole industry thought that the CM won't attend a film's music release event, MGR graced the function and launched the audio of 'Poovukkul Boogambam', as promised. Many celebrities came to attend the audio release after hearing about MGR's arrival. This is how the audio launch trend began in Kollywood by Thiagarajan.
