Giago founded The Lakota Times newspaper on the Pine Ridge Reservation. It became Indian Country Today, which was the largest independent Indian newspaper before being purchased by the Oneida Nation of New York.
Giago went on to start The Lakota Journal before his retirement in 2004. He continues to publish his "Notes from Indian Country" column in media outlets across the nation, including Indianz.Com and The Huffington Post.
Giago is the first Native American in the South Dakota Newspaper Hall of Fame.
