Question: The first game in Arena Football League history was played on June 19, 1987, between the Gladiators and Commandos at Pittsburgh Civic Arena in front of 12,117 fans. The game was deliberately not televised so that it could be analyzed and any follies and failures would not be subject to national public scrutiny. Following the inaugural game, tweaks and adjustments were made, and the first season continued. The Dynamite and Bruisers played in the first-ever televised AFL game the next night, on June 20, 1987, at the Rosemont Horizon in suburban Chicago on ESPN with Bob Rathbun and Lee Corso calling the play. The broadcast showed a short clip of the Commandos-Gladiators game. Each team played six games, two against each other team. The top two teams, Denver and Pittsburgh, then competed in the first-ever AFL championship game, ArenaBowl I.
Is there an answer to this question: At what venue did the first televised Arena Football League game occur?
