Why? Because it's all the same folk on a merry-go-round of channels. Whether it's Shop Extra, Shop on Tv, Seen on Tv, TJC's IW, or the defunct IW, they all have connections with the original company Ideal Shopping Direct and it's original Ideal World channel.
Shop Extra - Val Kaye & Paul Wright (The folks that started the original Ideal World) + ex ideal world staff/presenters/guests
Shop on TV - Jamie Martin & Martin Purcell (Head honchos at Ideal Shopping Direct, jumped ship before **** hit the fan) + ex ideal world staff/presenters/guests
Seen on TV - Ex ideal world staff/presenters/guests
TJC's Ideal World - Ex ideal world staff/presenters/guests
Defunct IW2 - all the staff/presenters/guests of Ideal Shopping direct.
Is it any wonder they are all similar?
