Fireman Sam (Welsh: Sam Tân) first broadcast on 17 November 1987 on the Welsh TV channel S4C.^[1] The series is set in the fictional Welsh town of Pontypandy, which was retconned from being a rural village in the south Wales valleys to being a larger seaside fishing town in the 2008 remake series.^[1] Other locations mentioned include Cardiff and Newtown.

Originally featuring a small cast of characters, with the later series the cast was expanded to a large range of supporting characters of diverse backgrounds and occupations.

Every episode includes an emergency of some kind in which the characters say "call Fireman Sam", with a moral lesson being learned at its conclusion.^[2]

The series features an ensemble cast of regular and recurring characters, and began with nine human characters in its first series. All the characters in the original series were voiced by John Alderton, roughly divided between children and adults. The original four firefighters; Fireman Sam, Elvis, Station Officer Steele and Trevor were introduced alongside three child characters, Sam's niece and nephew Sarah and James and naughty Norman Price.

The only other character introduced in the original run was the female firefighter Penny Morris who first appeared in Series 3.

In 2005, the revived series included all the old characters as well as new characters designed with the modern techniques of stop motion claymation. The Flood family was introduced consisting of Mike the Plumber, his wife Helen the Nurse, and their daughter Mandy. They were joined by Tom Thomas an Australian helicopter pilot. The main characters in this series were all voiced by John Sparkes, Joanna Ruiz and Sarah Hadland.

In 2008, the new CGI series saw the introduction of three new relatives of established characters; Sam's brother Charlie and his wife Bronwyn along with Norman's cousin Derek Price. The voice cast was also replaced, with the new voice actors for the series being Steven Kynman, Tegwen Tucker, David Carling and Su Douglas. With each new series since, more characters have been introduced including Bronwyn's train driver father Gareth Griffiths, Canadian adventurer Moose Roberts and the Chen and Sparkes families.

The animal characters have also played an important role in the series including dogs Dusty, Radar and Nipper, cats Rosa and Lion and sheep Woolly and Lambykins.
