Is the Sunday Times UK a tabloid newspaper?
Possibly. It just depends what you mean by tabloid – “tabloid” refers both to a newspaper page size and a style of journalism. Traditionally, tabloid-sized newspapers (The Sun, Daily Mirror) have had lots of sensationalised stories about crime, celebrities, royalty, sport etc; whereas broadsheet-sized papers (Times, Telegraph, Guardian and so on) contained more serious journalism. Hence the terms “tabloid journalism” and “broadsheet journalism”. Nowadays almost ALL newspapers (possibly including the Sunday Times, I haven’t read it recently) are tabloid in size, but the Sunday Times is definitely broadsheet (i.e. more serious) in journalistic content. However, over the last 15 years or so there has been a gradual “dumbing down” of the broadsheet papers (starting with the Times), so the likes of the Sunday Times now carry a lot of stories about celebrities and popular culture that 25 years ago you would only have found in something like the Sunday Mirror or News of the World.
