Replying to
@JPK_elmediat@mastodon.art @petersterne@mastodon.social @thatonecalculator@stop.voring.me that’s true – examples are
Sellotape, which everybody calls any kind of adhesive tape simply because it’s the leading brand here in the UK (hilariously, the leading brand in Australia is called Durex!)
Tarmac (which isn’t always made by that company)
Velcro (more correctly it should be referred to as a hook and loop fastener, unless actually made by that company)
JetSki (which is a trademark of Kawasaki, all others are merely personal water craft)
Heroin (Bayer & Co)
Hovercraft (Saunders Roe)
Videotape (Ampex)
Chromakey (Ultimatte – whereas the BBC steadfastly refers to it as CSO – colour separation overlay)
