In addition to his role as moderator for "SaReGaMa", Sonu also presented the television show "Kisme Kitna Hai Dum" and was a member of the jury for "Indian Idol" (Sony Entertainment Television) season 1, 2 and special member of the jury in relay 3. He was also a special member of the jury for "Amul Star Voice of India" in August 2007. In October 2007 he returned to the program "SaReGaMa" as a member of the jury along with Suresh Wadkar for "Sa Re Ga Ma Pa L'il Champs International".
In 2006 he presented the radio show "Life Ki Dhun with Sonu Niigaam" on Radiocity 91 FM. He took this opportunity to interview other great musicians such as the famous Mangeshkar Tin.
Sonu began his film career in his childhood with films like "Betaab" (1983). As an adult he has co-starred "Jaani Dushman: Ek Anokhi Kahani" alongside Sunny Deol, Manisha Koirala and Akshay Kumar, and starred in "Kash Aap Hamare Hote" alongside Juhi Babbar, daughter of Raj Babbar, and at the end of "Love in Nepal" next to Flora Saini and Sweta Keswani. Unfortunately, all these films did not have much public success, although the critics for "Love In Nepal" were very good. Since this film, Sonu has not participated in any other film, but currently he has some scripts in his house and it is said that maybe he is going to make the movie "Anhkhon Ankhon Main", where he would play the role of a blind singer.
