Question: What frequency is the magazine, in which the Texas Football Classic appears, published?

full_context: Document 1: Phil Steele: Phil Steele (born c. 1960) is an American sportswriter and analyst who focuses exclusively on college and professional football. He currently writes a column for the "Orlando Sentinel", and is considered a "highly respected prognosticator" within the sports media. His company, Phil Steele Publications, produces the annual preseason magazine "Phil Steele's College Football Preview", which he personally writes in almost its entirety. The first edition was published in 1995. In a comparison of the major preseason college football magazines, ESPN writer Pat Forde said:All the mags have their merits . . . But Phil Steele owns the genre . . . The 46-year-old uses a cookie-cutter layout for every team, and his writing will never be nominated for a Pulitzer. But he does author every two-page team preview himself, and he crams stats, facts and figures into every nook and cranny. The magazine was similarly praised by the "News & Observer" and Rivals.com. Chris Stassen, owner of football.stassen.com, has tracked the preseason magazines' accuracy since 1993 and rates "Phil Steele's" as the most accurate in its predictions.
Document 2: Red River State Fair Classic: The Red River State Fair Classic (formerly the State Fair Classic and, more recently, the Shreveport Classic) is an American college football game played annually in Shreveport, Louisiana, at Independence Stadium (formerly State Fair Stadium) during the State Fair of Louisiana.

By having first paired historically black colleges and universities in 1922, the contest holds the distinction of being the oldest annual black college football classic, edging out the Turkey Day Classic by two years and the similar Texas State Fair Classic by three years. Also, so far, the earliest documented use of the term "classic" as part of an annual black college football game's formal name has been dated to the 1927 Louisiana State Fair Classic.
