A couch is a sofa, such as people have in their sitting-rooms, often in front of the television. Some people spend a lot of time sitting on the couch watching television, and probably getting fat for want of exercise. We have a name for such people in English – couch potatoes. And, as British people are well known for watching TV a lot, perhaps we are a nation of couch potatoes. Google, the company that runs the internet search engine, has just published a survey which claims that British people now spend more time on the internet than they do watching television – 164 minutes a day on average on the internet, 148 minutes watching television.
