There is no single guide that lists all the current television miniseries on each channel. However, viewers can get access to information about current miniseries and other shows on each channel's website or Wikipedia page. These pages show the currently airing comedies, dramas and miniseries.
Wikipedia provides information on the list of programs broadcast by HBO. The channel is not currently airing any miniseries. However, the page shows that miniseries such as “Show Me a Hero,” “The Jinx” and “The Casual Vacancy” aired in 2015, while “Oliver Kitteridge” and “Sonic Highways” aired in 2014.
Similarly, Starz does not have any currently airing miniseries. But the channel televised “Flesh and Bone” in 2015, “Torchwood: Miracle Day” in 2011 and “The Pillars of the Earth” in 2010.
