I enjoy watching Gruen, but tonight on 30 Oct 2019 I was disappointed that there were 2 advertisements aired in relation to the origion of Halloween, which they incorrectly stated originated in the USA.
"Halloween's origins date back to the ancient Celtic festival of Samhain (pronounced sow-in). The Celts, who lived 2,000 years ago, mostly in the area that is now Ireland, the United Kingdom and northern France, celebrated their new year on November 1."
Maybe the producers could make sure the information in the advertisements is correct, before they go to air!
