KEY POINTS:
R. Michael Kammerer jnr, who put some of the millions he made in the cable television industry behind an effort to find the final resting place of famed pilot Amelia Earhart, has died. He was 67.
In 2001, he got involved in the search for Earhart's Lockheed Electra on the ocean floor near Howland Island, a Pacific refuelling stop just a few kilometres north of the equator. Earhart's flight in 1937 captured the imagination of people all over the world, and her disappearance resulted in decades of debate over where the plane went down.
Kammerer spent two decades in advertising before he founded ITN in 1983 from a basement office in his family's home in Chappaqua, New York. The company expanded to become one of the largest suppliers of non-network, primetime advertising in the United States.
