O&Os tend to be found in large urban centers such as New York City, Los Angeles, and Chicago, and other markets that are typically among the 10 largest in the U.S. (such as the San Francisco Bay Area, Dallas–Fort Worth, Philadelphia, and Houston), although they have also been found in markets as small as Green Bay, Wisconsin (DMA #69, 2006–07) and Toledo, Ohio (DMA #76, 1995–2011) in the past. Some networks (such as Ion Television) and non-commercial religious television networks (such as the Trinity Broadcasting Network and Daystar) own the vast majority of their stations, with only a few privately owned outlets carrying their programming (in the case of TBN and Daystar, both networks own their stations directly and through subsidiary licensees, such as Community Educational Television for TBN and Word of God Fellowship for Daystar).
