Azumanga Daioh was a Japanese slice of life/comedy anime series that aired in Japan from April 8th-September 30th, 2002 on TV Tokyo. The show aired in five minute segments, which were compiled into 26 episodes and sold as DVDs and UMDs in Japan by Starchild Records.
The Animax dub of Azumanga Daioh aired in 2012 as seen in the commercials of the show. An interesting thing to note is that the commercials used not only the Animax English dub, but also used sounds from the original Japanese version. The commercials also show us that the show was meant to air on a TV channel called AniChan from Monday to Friday at 4:00pm JKT/BKK. The dub features a completely different voice cast and many changes, such as Ayumu "Osaka" Kasuga being voiced with a more "standard" English dialect, as opposed to the southern drawl featured in ADV Films' dub (itself an attempt at localizing stereotypes about the Osaka region of Japan to an American audience).
As of now, only four out of 26 episodes from the Animax dub has been found, that being episodes 2, 3, 5, and 6 of the anime. The others have yet to resurface online, and it is unknown if the dub was released onto DVDs.
Animax have produced multiple dubs of series that have alternate English Dubs. As a subsidiary of Sony Entertainment, their dubs are owned by Sony, which is why a lot of them don't see home releases. Their dubs are probably recorded in Singapore (through Odex Pte. Ltd) or Hong Kong, and cast ex-pats, most of whom have no prior acting experience. The company is also known for producing quick and cheap dubs, which could be another factor as to why some of them are never released onto home video.
