The 5.6-million audience of BBC1's The One Show will be treated to the finest sights of the town, including the Mere's Mouth, Market Square and views looking out from the top of St Mary's Church.

The cameras rolled into town on Monday with former England cricketer Phil Tufnell presenting a feature called The Name Game, trying to explain the origin of Diss' name.

Town mayor Simon Olander hopes the feature will help promote Diss and attract more visitors to the town.

He said: "It's very good for Diss and might get people back shopping in the town and get them interested in what it has to offer.

"We've had Phil Tufnell and the film crew here in the same week as Kelly Holmes' visit to the town, so these things are good for Diss. It is hopefully going to put the town on the map."

Diss museum manager Basil Abbott, who took part in the filming session, said: "I'm always pleased to see Diss being promoted and I'm sure it will help to bring more visitors to the town."

Other local figures including Diss historian Clifford Bird, St Mary's Church rector Tony Billett, and scrap metal dealer Pete Gillings, were interviewed to put forward their own theories for the town's name.

The film crew's director, Jon Doyle, said: "What we had in Diss was at least two theories for the origin of the name that could make a good feature.

"It is an interesting place name and quite amusing," he added, referring to the modern slang usage of 'diss' as a term of disrespect

"It helped that we were blessed with some nice weather and we were given access to some great places. We got on top of the St Mary's Church and got some lovely views and shots of Diss and the Mere.

"I'm really pleased with what we filmed because I wasn't sure what to expect from the town but we had a great day. I'm sure it will make a fine piece."

Mr Tufnell, winer of the 2003 I'm A Celebrity... Get Me Out Of Here! celebrity TV show, seemed to be impressed with the town too. He said: "It looks like a very nice country town and it's good to see the Mere with the children fishing in it.

"I'm sure I will be trying out one of the local pubs at lunchtime too."

Diss will be featured along with other towns and villages with interesting theories as to how they got their names, including Pity Me in County Durham, Wetwang in Yorkshire and Ramsbottom in Lancashire.

The Diss feature is likely to be aired in the last week of February on The One Show, BBC1 at 7pm on a weekday evening.

How did Diss get its name?

From the town's earliest settler called Dic, possibly a Viking?

From the Anglo Saxon word for ditch or dyke. However, nowhere else has that in the name, even though there were ditches and dykes everywhere?

A more elaborate theory is the name originating from Dis Pater, the Roman and Celtic God of the underworld. Surely the Mere's Mouth is not a gateway into the infernal regions?
