The circulation of USA Today, Gannett Co.'s new national newspaper, is exceeding projections after a month on the newsstands and will be introduced in two additional market areas ahead of schedule, Gannett Chairman Allen H. Neuharth said yesterday.

The average daily paid circulation in the first two weeks of October was 221,978, he said. Gannett's five-year plan for the development of the paper projected a circulation of 200,000 by the end of this year.

As a result of the encouraging response from both readers and advertisers, the paper will be introduced in the Seattle-Portland corridor on Nov. 8 and in the San Francisco-Sacramento area on Nov. 15, instead of next year as originally scheduled, Neuharth said. USA Today is sold in the metropolitan areas of Washington, Baltimore, Atlanta, Pittsburgh and Minneapolis-St. Paul.

Nueharth said papers for the Pacific Northwest will be produced in the plant of the Daily Olympian, a Gannett newspaper in Olympia, Wash. The Northern California edition will be printed at the San Rafael Independent-Journal, another Gannett daily.

Neuharth said that "one month's experience in five markets is too limited to predict the degree of ultimate success of USA Today."
