I have only ever seen adverts for both. IMO though it is one hundred times worse.
Ever since Sir John Hall, once owner of Newcastle United, decided to claim the term Geordie as only having anything to do with NUFC (historically very incorrect), and invent the fictional 'Gerodie Nation', modern day 'Geordies' go out of their way to 'soond as styoopad' and OTT as possible.

95% of people on Tyneside live nothing like those fools. The city centre is nice, most surrounding areas are a dump!
Not to mention that apparently only two of the characters on this programme are from the area they claim. One is from Sunderland, one Washington (part of Sunderland), one South Shields (Sunderland) and one Middlesbrough by all accounts

As for Made in Chelsea, surely a lot more of the population are pretentious rich kids like these seem to be? As it is a far more affluent area to begin with.
Or is that not what it is really about?
