"Vibrant and fiercely independent media in our country is an asset for all of us. It has served us well in disseminating information, educating the public and keeping a critical eye on the work of the government," he said speaking at a function here to mark 125 years of the Malayala Manorama group.
Singh said that while the media has grown in size and evolved, some "aberrations" have also crept in.
"But the good thing is that these aberrations are also being discussed and debated. It is for media itself to find ways and means to removing the deficiencies which it suffers from," he added.
Speaking on the occasion, Defence Minister A K Antony said the country was witnessing a "transparency revolution".

"There is need and urgency that this revolution percolates all institutions in the country," Antony said.
Chief Editor of Malayala Manorama Mammen Mathew noted that the group had been established in the pre-Independence era when it espoused social justice and nationalist causes.
Jacob Mathew, Executive Editor of Malayala Manorama, said while the group traversed years and decades, its mandate of being the voice of responsible journalism and credibility, remained unchanged.
