The nation’s largest cigarette maker, Altria Group Inc.'s Philip
Morris USA, has failed in yet another attempt to sell Americans
on a potentially safer cigarette, pulling the plug on Marlboro
Ultra Smooth, a version of Marlboro that used a high-technology
filter.
What does Pullig the Plug means???
I am brazilian, my english is poor, but I want to learn more and more! Is it meaning that the Marlboro Ultra Smooth brand is to be discontinued?
When you pull the plug, you cut off electricity supply to the electrical appliance by removing its plug from the wall socket.
I guess you can guess what “pull the plug on something” means idiomatically.
Also, you can refer to this explanation: thefreedictionary.com/pull+the+plug
“Having so effectively answered the question, lost_soul has all but pulled the plug on this thread.”
(an example of how one might use that phrase in everyday speech)
