are now stages 31 and 32. The show's production staff included art director Matt Jefferies, who designed the starship Enterprise and most of its interiors. His contributions to the series were honored in the name of the "Jefferies tube", an equipment shaft depicted in various Star Trek series. In addition to working with his brother, John Jefferies, to create the hand-held phaser weapons of Star Trek, Jefferies also developed the set design for the bridge of the Enterprise (which was based on an earlier design by Pato Guzman). Jefferies used his practical experience as an airman during World War II and his knowledge of aircraft design to devise a sleek, functional, and ergonomic bridge layout. The costume designer for Star Trek, Bill Theiss, created the striking look of the Starfleet uniforms for the Enterprise, the costumes for female guest stars, and for various aliens, including the Klingons, Vulcans, Romulans, Tellarites, Andorians, and Gideonites, among others.

Chang also designed the portable sensing-recording-computing "tricorder" device, and various fictitious devices for the starship's engineering crew and its sick bay. As the series progressed, he helped to create various memorable aliens, such as the Gorn and the Horta.

Reviews were mixed; while The Philadelphia Inquirer and San Francisco Chronicle liked the new show, The New York Times and The Boston Globe were less favorable, and Variety predicted that it "won't work", calling it "an incredible and dreary mess of confusion and complexities". Debuting against mostly reruns, Star Trek easily won its time slot with a 40.6 share. The following week against new programming, however, the show fell to second (29.4 share) behind CBS. It ranked 33rd (out of 94 programs) over the next two weeks, then the following two episodes ranked 51st in the ratings. Frederik Pohl, editor of Galaxy Science Fiction, wrote in February 1967 of his amazement that Star Treks "regular shows were just as good" as the
