Discovery and channels like these provide useful information on a wide range of subjects making us more aware of the world we live in. Its program content is so diverse that there will be something for you no matter what your interests are. It is specially good for young children who should be kept away from awful so-called cartoon channels that promote violence and aggresiveness.
Just as bad as the saas-bahu serials that cannot be further away from reality and the only concept they promote is infedility and jealousy. Amidst all these, Discovery and National Geographic stand out as a beacon of light from a lighthouse, promising to deliver us from stromy seas.
