Mr. Pramod Mathur, the maker of the famous DD show 'aisa bhi ho sakta hai', had told that he had plans to revive/continue the show, and even plans to bring in novel concepts for new shows i think, but he had to forego all of them as DD simply didn't seem interested, and due to the prevailing corruption.
Perhaps we could create a petition, citing the link above, and ask the Govt. to look into the matter, and help infuse a new life and vigour into this ailing elephant, and either bring back those superb shows from the annals of history, or/and give chance and space to talent in the industry to create similar shows, a league apart from what other channels have been dishing out. when the viewership of DD would increase, other channels might be forced to rethink, and we may then see a change in the overall scenario for good!
But, being too optimistic perhaps!
