The series has aired in Canada on Teletoon, in the United States on Qubo, in Australia on ABC3, in the United Kingdom on Nicktoons, in Latin America on Disney XD, and in Sweden on Nickelodeon.

Digital television: Digital television (DTV) is the transmission of television signals, including the sound channel, using digital encoding, in contrast to the earlier television technology, analog television, in which the video and audio are carried by analog signals.  It is an innovative service that represents the first significant evolution in television technology since color television in the 1950s.  Digital TV can transmit multiple channels in the same bandwidth occupied by a single channel of analog television.  A switchover from analog to digital broadcasting began around 2006 in some countries, and many industrial countries have now completed the changeover, while other countries are in various stages of adaptation.  Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widely used standards:

Lower Your Eyelids to Die with the Sun: The video for "Lower Your Eyelids to Die with the Sun," directed by Yoonha Park, was released manually by Gonzalez himself via M83's YouTube channel on 21 August 2014.  The video, which cut the song down to 8 minutes, features spliced footage of crash test dummies in use interspersed with a man and a woman, as well as their personal belongings (a purse, a pill bottle, a coffee mug, a makeup brush, etc.), being thrown from their cars in slow-motion with the glass from their windows as well as their belongings cascading around them.  The video closes with their death and ascends into computer-generated nebulae.  The video is in-keeping with the album-wide theme of car crashes, as seen on the songs ""Don't Save Us From the Flames"" and ""Car Chase Terror"".  The video was praised, Pitchfork media calling it "all very cinematic and beautiful," as well as Stereogum saying that it is "as majestic and somber as the song itself."  It is currently the 4th most viewed video of theirs on YouTube.

Nicktoons (UK and Ireland): Nicktoons is a British/Irish digital television channel, launched on 22 July 2002.  It is a cartoon based sister channel to Nickelodeon.  The channel airs Nicktoons, as well as acquired programming from outside providers.  Unlike the United States version, it has been ad-supported since launch.

Indigenous Community Television: Indigenous Community Television (ICTV) is an Australian free-to-view digital television channel on the Viewer Access Satellite Television service.  It broadcasts television programs produced by, and for, indigenous people in remote communities.  The channel is owned by membership-based company Indigenous Community Television Limited.  Although ICTV is a community television channel by name and content, it broadcasts using an open-narrowcast licence instead of a standard community television licence.

9HD: 9HD is an Australian television channel, owned by Nine Entertainment Co., originally launched on 17 March 2008 featuring unique "breakaway" programming until 2009 and a HD simulcast of the Nine Network from 2009-2010 and again since 26 November 2015.  The channel is available on high definition digital television viewers in metropolitan and regional areas through a number of owned-and-operated and affiliate stations.  Originally 9HD only simulcast blocks of programming from the Nine Network, and in 2008 it added time-shifted news, movies, drama and entertainment programs.  Following the launch of GO!  in August 2009, 9HD reverted to a HD simulcast of the Nine Network.  The channel was replaced completely in 2010 and the space occupied by the newly launched multichannel GEM.  Following the government's decision to remove the SD Primary Channel limitations, the channel returned as a HD simulcast on channel 90 on 26 November 2015.

RTL Telekids: RTL Telekids is the name of a digital television channel for children.  The channel is operated by RTL Nederland and can be received through cable.  In addition, RTL Telekids is broadcasting as a youth block on television channel RTL 8 during daytime.  Like the rest of the Dutch RTL family RTL Telekids is officially a Luxembourg channel that does not have to adhere to the Dutch media law.  As Luxembourg has no real regulator, the channel is also not monitored.

Chesterfield transmitting station: The Chesterfield transmitting station is a television and radio transmitter which serves the town of Chesterfield in Derbyshire and surrounding areas.  It transmits digital television which it is line fed from Sheffield (Crosspool) (also known as the Tapton Hill transmitting station).  The Chesterfield transmitter sits on a hillside to the north of the town and transmits digital television and radio services.  Before the digital switchover, it was one of the few transmitters in the UK to transmit digital television but not analogue channel, Channel 5, and a number of its digital multiplexes were transmitted on the same channels as Emley Moor so it was not uncommon for co-channel interference to be a problem; similar problems still exist with Sutton Coldfield and Waltham (see external links).  These co-channel issues with Emley meant that its output was attenuated to the North.

Metro Gold: Metro Gold, also known as 9 Gold, was a Hindi-language terrestrial television channel in India.  The channel was a joint venture of both DD Metro and Nine Gold of Kerry Packer and Vinay Maloo HFCL - Nine Broadcasting India; hence known as Metro Gold.  During its first launch, the channel was more likely known as DD Metro channel's "primetime block" from 7 pm to 10 pm IST, where it showed its programmes only in the given three-hour span on DD Metro Channel.  But when the programmes started becoming popular in the primetime slot, DD Metro tried to set up some realistic terms with Nine Gold, which created disagreement between the companies and led up the channel's closing.
