Forget about being well-read, knowing your stuff about TV shows is the new way to show off at the dinner table.

'Ice rinks fill up when Dancing On Ice is on, people rush out to buy books featured on TV, ingredients on cookery shows sell out completely and people redesign their gardens and houses based on TV.'

Television shows such as Breaking Bad and Broadchurch are more likely to get people talking than a new book.
