Battlestar Galactica's first season of thirteen one-hour episodes was ordered by the Sci-Fi Channel on February 10, 2004, with production taking place in Vancouver, British Columbia, Canada. Produced in 2004 by David Eick and Ronald D. Moore, and starring the original cast from the 2003 miniseries, it began airing in the United Kingdom and Ireland on October 18, 2004. The series proved successful, attracting favorable comments from reviewers, and generating considerable anticipation in the U.S.
It began airing in North America three months later, on January 14, 2005 in the United States, and January 15 in Canada. The first episode aired in the U.S. became one of the highest-rated programs ever on Sci-Fi, with 3.1 million viewers. The series' first season became the network's highest-rated original series to date.
Battlestar Galactica's first episode was later made available for viewing in its entirety, and without charge from the Sci-Fi website. Moore also sought to address the "Internet Generation" by posting podcast commentaries on individual episodes on the official Sci-Fi website.
In its statement accompanying the announcement of the show's Peabody Award, the Peabody Board noted "Battlestar Galactica is not just another apocalyptic vision of the future but an intense drama that poses provocative questions regarding religion, politics, sex and what it truly means to be 'human'.... Writers Ronald D. Moore, Toni Graphia, David Weddle, Bradley Thompson, Carla Robinson, Jeff Vlaming, Michael Angeli, and David Eick take full advantage to give us plotlines that are deeply personal and relatable, while never compromising their affinity and passion for science fiction".
The first season was released on DVD in region 1 on September 20, 2005, in region 2 on March 28, 2005 and in region 4 on August 15, 2006. It was also released in region 1 in HD DVD on December 4, 2007 and on Blu-ray Disc on January 5, 2010.
The sets include all 13 episodes of the first season and the miniseries. Special features include commentary on the miniseries and "33" by executive producers Ronald D. Moore, David Eick and director Michael Rymer. Moore and Eick provide commentaries for "Bastille Day", "Act of Contrition" and "You Can't Go Home Again". Beginning with episode 9, Moore began recording podcast commentaries for the episodes on the official Battlestar Galactica website; Moore provides commentaries for "Tigh Me Up, Tigh Me Down", "The Hand of God", "Colonial Day", "Kobol's Last Gleaming (Part 1)" and "Kobol's Last Gleaming (Part 2)".
