Doonesbury began as a continuation of Bull Tales, which appeared in the Yale
University student newspaper, the Yale Daily News, from 1968 to 1970. It focused
on local campus events at Yale. It became a daily strip in twenty-eight newspapers
and was the first strip from Universal Press Syndicate. A Sunday strip began on
March 21, 1971. The strip became known for its social and political commentary
and is one of the longest running comic strips of all time.

Doonesbury is written and penciled by Garry Trudeau, then inked and lettered
by an assistant:Don Carlton then Todd Pound. Sunday strips are colored in by
George Corsillo.
