SINCLAIR REVISES THIRD QUARTER REVENUE ESTIMATES

Company to Report Final Third Quarter Results on November 4, 2004

                BALTIMORE (October 4, 2004) - Sinclair Broadcast Group, Inc. (Nasdaq: SBGI) announced today that it is revising its net broadcast revenue estimate for the third quarter ended September 30, 2004.

                Initial guidance was for third quarter net broadcast revenues to be up 4% to 5% from third quarter 2003 net broadcast revenues of $161.3 million. However, due to weakness primarily in auto advertising spending and cancellations resulting from the recent hurricanes which impacted eight of the Company’s television stations in the Southeast, the Company is revising its net broadcast revenue guidance to be approximately $163.7 million in the third quarter.

                Sinclair will release final third quarter 2004 earnings results on Thursday, November 4, 2004 at 7:30 am ET.
