Re the comment by Ithinkitsjustme Tbh, it doesn't bother me in the slightest. It's not a newspaper (and I use the words loosely!) that I or anyone I know read
The Sun newspaper has the biggest circulation in Britain = the largest readership of any British newspaper, average daily readership of 7.6 million people per day. It is, sadly, highly influential. For example, from 'only backing the winner' when it comes to Prime Ministers and general elections, to socio-economic - and feminist - attitudes among readers.
I was a tabloid journalist once, and I used to know the people who worked on the 'Page 3' desk. Interestingly Page 3 glamour models were not well paid, at least 5 years ago. The going rate then was no more than £300. While being a Page 3 model the models had to be exclusive to The Sun, and could not appear in any other newspaper (the monthly men's magazines were allowed). Although Page 3 has a strict 'no implants' rule, the models' bodies and faces were photo-shopped to within an inch of their lives.
I think the prevailing attitude among staff at The Sun is that Page 3 is outdated, tacky and naff, but to get rid of it would be conceding to the liberals and 'hairy feminists' to too much of an extent for them, and readers, to swallow. I think they just couldn't bear the humiliation of the nation celebrating the end of Page 3.
I think a good angle that would help get rid of Page 3 is to target the many A-list celebrities who appear in the newspaper, give it exclusive interviews and exclusive downloads, trailers and photo-shoots, to promote their music and films. Lots of women artists, actors and so on who are seen as empowered women sign up to work with The Sun on promotional matters (because it has such a huge readership = they sell more records; their record companies, film and PR companies put The Sun at the top of their press-campaign lists).
If those celebrities boycotted The Sun until it got rid of Page 3, I think that would put strong pressure on the newspaper's editorial staff to act.
