Founded by R. D. (Dave) Walker, publisher and editor, and aided by key team members Ali Khan, Curtis Lang, and Jan Vanschuyver Walker, the first issue of 116 pages was successfully launched with a 300,000 direct mail charter subscription offer that pulled a response rate of double the industry standard of 2%.  The original name was chosen because a d/b/a had already been formed under the name Houston City Magazine by David Crossley and Tom Curtis (although they had not actually published a magazine by this title).  A 51% interest in the magazine was purchased by "Texas Parade" in 1978, and upon the hiring of Crossley and Curtis it was subsequently re-titled "Houston City Magazine."

Southwest Media also owned "D Magazine" of Dallas, "Texas Homes" and "Sport Magazine".  In 1987, during a major downturn in Houston's economy, the magazine was sold to "Texas Monthly," who then killed one of their two major competitors (the other being "D Magazine" in Dallas).
