<P> The story numbers below are not official designations; they are meant as a rough guide to placement in the overall context of the programme . There is some dispute, for instance, about whether to count Season 23's The Trial of a Time Lord as one or as four serials, and whether the unfinished serial Shada should be included . The numbering scheme in this list reflects an internal practice of describing "Planet of the Dead" (2009) as the 200th story . Other sources, such as the Region 1 classic Doctor Who DVD releases, use different numbering schemes, which diverge after the 108th story, The Horns of Nimon (1979--1980). </P> <P> The following table dictates the season or series in question for the programme as a whole; singular specials are not included in episode counts or viewer totals . </P> <Table> <Tr> <Th_colspan="2"> Season / Series </Th> <Th> Era </Th> <Th> Doctor </Th> <Th> Serials </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> <Th> Average viewers (millions) </Th> </Tr> <Tr> <Th> First aired </Th> <Th> Last aired </Th> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> Season 1 </Td> <Td> Classic era </Td> <Td> First Doctor </Td> <Td> 8 </Td> <Td_colspan="2"> 42 </Td> <Td_colspan="1"> 23 November 1963 (1963 -
