Mumbai, Nov 21 (TIWN) Every year, November 21 is observed as World Television Day that emphasises how TV plays a vital role in presenting different issues that affect people. It was initiated by the United Nations in December 1996.

If we look back there are a lot of changes in terms of shows and techniques on television. Who can forget watching special serials like 'Mahabharat' or children's favourite 'Jungle Book' and its popular track 'Jungle Jungle Baat Chali Hai' with lyrics by Gulzar.
