"I very much doubt Mo Farah (for instance) decided to become a runner because he wanted to be famous - he just wanted to win races. JK Rowling didn't write the first Harry Potter book because she yearned to become a celebrity.
There's a big difference between people who are famous because they are very well-known due to their success and achievements, and those who are a 'celebrity' because they've married a premiership footballer or been on some reality tv show.
Be honest... if there is no story about someone the editor wants to mention, do they make one up?"
@sycamorecottage Right but how many stories do you see about Mo Farrah or JK Rowling on a regular basis?
Especially at the beginning of their careers, however, when they began to take off, they did do interviews and those interviews included their personal lives eg the fact JKR was a single mother when she wrote those books.
Doing those interviews helped them get more publicity and therefore more success in terms of sales/sponsorship/whatever.
Also in Hollywood if there is "buzz" around you - eg publicity - you're more likely to get cast in things. So a lot of celebs actively want to keep their names in the papers lest they become irrelevant.
And no, it absolutely doesn't work the way round of - we want to write about X so we'll make one up. There's got to be a narrative, whether it's a divorce/fling/whatever. That's what makes it compelling.
