2000: On the day following cartoonist Charles M. Schulz's death of a heart attack, the last ever "Peanuts" strip runs in papers. Schulz, who had been battling health issues and was diagnosed with colon cancer in late 1999, had retired from drawing the strip in December 1999, with the last daily strip appearing on Jan. 3, 2000. At that point, five more original Sunday edition "Peanuts" strips had yet to be published. The very last strip consisted simply of Snoopy sitting at his typewriter in thought with a note from Schulz explaining his retirement and thanking his fans.
