Be aware that the video linked in the article has 1 use of strong language and some disturbing images, as it frankly tackles the social impact of the normative sexualisation of females across our media, not least advertising.
Can such campaigns work? Media content won't be transformed by this, but it will increase awareness of the issue and maybe lead to more single issue campaigns such as the anti-page 3 campaign that has seen topless, often teen, models removed from The S*n, with Murdoch himself tweeting that this was maybe an idea beyond its time.
The difficulty of addressing such issues without being censored by the very same media that are being protested against is notable, with social media offering a distribution outlet independent of the old media giants (all of which are gradually being dwarfed by the new media giants though!)
(The S*n hasn't exactly gone PC; it recently invited readers to submit cleavage selfies for a boobs of Britain competition. Unilad reported on some of the satirical responses this generated, often men photographing their chests; as with the video, be aware that there are sexualised images, and that comments, as with so much of social media, are often crude. http://www.unilad.co.uk/viral/the-sun-asks-women-for-cleavage-selfies-gets-brilliantly-trolled/)
