That certain class of broadcast (irrespective of medium) which purports to be true and complete information but has been manipulated, filtered and censored by corporations, government agencies and any other parties wealthy or influential enough to access corporate media decision makers. Knews usually advertises itself using slogans that suggest very strongly that its presenters and content can be "trusted" or that the viewer can make his own decision about what he will see.

Knews is one of the main products of a governmedia and differentiated from infotainment in that it is focused on national, international or political events rather than celebrities, sports or other trivial pursuits. Knews (pronounced: `k-news) represents itself as "news" but has a diluted basis in reality (if any). If the producers of knews haven't totally fabricated its content, they have distorted the meaning of real events until the final product is more closely representative of propaganda.
