From the temple fairs and markets frequented by the potion pedlars of yesteryear, to the department stores and supermarkets of a later era, to the home shopping networks on cable today, salesmen have been making pitches peppered with interesting local expressions and slang (mostly in Taiwanese). These give the new sales programs a distinctly grassroots and down-home feeling.
從早年廟會、菜市場走江湖、賣膏藥的叫賣，到後來百貨公司、超級市場的產品展示，一直到目前第四台的空中推銷，都穿插了地方語言（其中以閩南語為大宗）的趣味性，這也使台灣絕大部分的電視購物節目具有草根性和鄉土氣息。
