Mason is part of the Cincinnati media market. Although
no broadcast stations are licensed to Mason itself, the city is

WLW (700 Cincinnati), which uses one of only seven remaining Blaw-Knox
diamond-shaped towers.
Clear Channel Communications (NYSE: CCU) is a media company based
in the United States of America. Clear Channel, founded in 1972
by Lowry Mays and Red McCombs, wields considerable influence in
radio broadcasting, concert promotion and hosting, and fixed advertising
in the United States through its subsidiaries. The company owns
over 1,100 full-power AM, FM, and shortwave radio stations, ten
satellite radio channels on XM Satellite Radio, and more than
30 television stations in the United States, among other media
outlets in other countries. The present head of the company is
Mark Mays, and its headquarters is located in San Antonio, Texas.
The term "clear channel" comes from
AM broadcasting, referring to a channel (frequency) on which only
one station transmits. In U.S. and Canadian broadcasting history,
"clear channel" (or class I-A) stations had exclusive
rights to their frequencies throughout most of the continent at
night, when AM stations travel very far due to skywave. WOAI in
San Antonio, one of Clear Channel's first acquisitions, was such
a station.
