CNN Presents is an American documentary program on CNN weekends. The program used to be replaced with CNN Special Investigations Unit, which features the same documentary format, but expands upon it in a number of ways and is shorter in length. The program is a regular weekly series that looks in-depth in the important news stories of the times. Notably, the program has been a winner of a number of different awards, including the International Documentary Association Best Documentary Series award. Previous to his departure from CNN, Presents was hosted and narrated by Aaron Brown. While CNN Presents was broadcast on the network, a specialized CNN Presents logo was shown in the corner without the news ticker on the screen. CNN Presents has been revived since its presentation of God's Warriors by Christiane Amanpour in August 2007, and later with Planet in Peril and Black in America.
