Reese Schonfeld, who founded the Cable News Network (CNN) with Ted Turner in the early 1980s before developing another major cable channel, the Food Network, a decade later, died July 28 at his home in Manhattan. He was 88.

Mr. Turner and Mr. Schonfeld gambled that CNN could effectively challenge the three main broadcast networks in their news coverage, which at the time consisted largely of 30-minute evening newscasts.

In 1975, he started the Independent Television News Association, which provided news footage to local news stations. Later he founded the Food Network, which is now part of global entertainment.
