And: "The name 'Wispa', which is a combination of 'wisp' and 'whisper', was chosen to reflect the 'textual experience'."
Apparently, the first Wispas were deemed too big for a 'lady' to fit in her mouth, so were scaled down!
A Wispa cost 16p back in 1983. And they were actually very yummy indeed as I remember.
I remember a funny Wispa TV ad with Ruth Madoc and Simon Cadell of Hi De Hi fame - in this instance Gladys Pugh and Jeffrey Fairbrother in character, though not in name. The newspaper article below, by News Of The World TV critic Nina Myskow, dates from November 11 1984 and indicates that the Ruth/Simon ad was new on screen at that time.
There was an irritating (I thought) bloke whispering about Wispa on each and every ad - saying "bite it and believe it".
Below is the (thankfully silent) newspaper version from December 1984, which carried a 3p off coupon.
Badges from Wispa's early days.
Note that the right side of the 'W' is higher than the left. This was the original Wispa logo design. The 'W' was later regularised.
The interest was sparked by 1980s nostalgia and desire to re-experience this rather nice bar of chocolate. One of the advertising slogans for the relaunch was: "Some Things Are Best Left In The 80's... Others Aren't". The return of the Wispa proved so popular that Cadbury's brought it back permanently in October 2008.
A clever ad from the relaunch, name-checking many items of 1980s pop culture.
Get 'em whilst you can! But now Wispa is back for good.
More yum fun - the Cadbury's chocolate block mug was also new in 1983.
