There are two kinds of newspapers in Britain. One is large kind and has many detailed articles about national and international events. These newspapers are called serious papers or quality papers. The other kind, called the tabloids are smaller in size, have more pictures and shorter articles, often about less important events or about the private lives of well-known people. Though some people disapprove of tabloids, they are quite popular. Many people buy tabloids like The Sun which is the biggest-selling newspaper in Britain.
In all parts of the country there are also papers giving information about films* concerts and other things that are happening in the local area. Some local newspapers are free. These contain a Jot of advertisements and also some news. National serious newspapers like The Times or The Daily Telegraph generally give information about events happening in London. Most national newspapers express a political opinion.
Daily newspapers are published on every day of the week except Sunday. Sunday newspapers are larger than daily ones. They often have 2 or 3 sections. All Sunday newspapers are national.
