The thread is actually wrong on the campaign cost, which might be attributable to the AI-powered summarisation the tweet author boasts about. Norway spent 30m kroner (NOK) on the campaign, which is about $3.75 million instead of the $30m the tweet claims. And the thread misses out the potential return on investment: Norwegian salmon imports to Japan went from 400 million NOK before the campaign, to 1.8 billion NOK in the second half of the 80's.
