class="mw-editsection-bracket">]</span></span></div> <p>WTTW has been recognized as a pioneer in technical aspects of television broadcasting, particularly in broadcast audio transmission. The station, in particular, participated in the trend of pop music-focused programs on television during the early 1970s (a few of which were also simulcast on local FM radio stations). When WTTW began production on <i>Made in Chicago</i>, the station made the decision to transition from <a href="/wiki/Monaural_audio" class="mw-redirect" title="Monaural audio">monaural audio</a> to stereo for the FM broadcasts. However, stereo recording equipment for television production did not exist at that time. Because of this, WTTW engineers chose to modify existing <a href="/wiki/Ampex" title="Ampex">Ampex</a> <a href="/wiki/Quadruplex_videotape" title="Quadruplex videotape">quadruplex</a> recorders to provide a stereo medium in sync with the video portion of the program. This innovation earned the station's staff a local Technical <a href="/wiki/Emmy_Award" class="mw-redirect" title="Emmy Award">Emmy Award</a> in 1973. </p><p>Further refinements to this system resulted in improvements to both frequency response and <a href="/wiki/Noise_reduction" title="Noise reduction">noise reduction</a>, and eventually led to the ability to edit stereo audio as the video was being edited electronically. <a href="/wiki/Dolby_Laboratories" class="mw-redirect" title="Dolby Laboratories">Dolby Laboratories</a> noise reduction technology (Type C, and then Type A) was introduced as the staff was driven to make improvements in the audio specifications. WTTW began syndicating <i>Made in Chicago</i> to other public television stations under the new title <i>Soundstage</i>, with the first official taping of that program in June 1974 featuring previously filmed concert footage of folk singer <a href="/wiki/Jim_Croce" title="Jim Croce">Jim Croce</a> prior to his death in a plane crash in September 1973. The station was broadcast in simulcast FM stereo—with <a href="/wiki/WXRT" title="WXRT">WXRT</a> (93.1 FM) and <a href="/wiki/WBBM-FM" title="WBBM-FM">WBBM-FM</a> (96.3) as participating stations—in the manner of its predecessor. </p><p>In 1975, WTTW management was approached by a startup company called Telesonics with an idea to develop an audio system for television broadcasts that used a mono-compatible, stereo audio channel. Around this time, the Sears Tower had been completed and WTTW became one of the first broadcasters to move its transmitter facilities atop the new building; WTTW had broadcast from a temporary antenna as the now familiar twin towers that adorn the top of the building had not yet been completed.<sup id="cite_ref-31" class="reference"><a href="#cite_note-31"><span class="cite-bracket">[</span>31<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Programming">Programming</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=WTTW&action=edit&section=3" title="Edit section: Programming"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>WTTW carries programs distributed by PBS, <a href="/wiki/American_Public_Television" title="American Public Television">American Public Television</a> and other sources, along with airing several locally produced programs. WTTW also distributes several programs to public television stations independently of PBS, such as via American Public Television. In addition, WTTW is one of the few public television stations that regularly produce or present national public television programming. Its most prominent productions include political discussion program <i><a href="/wiki/The_McLaughlin_Group" title="The McLaughlin Group">The McLaughlin Group</a></i> and the music program <i><a href="/wiki/Soundstage_(TV_series)" title="Soundstage (TV series)">Soundstage</a></i>.
