Part of the campaign for Child's Eyes & No More Page 3 was to contact those advertising in The Sun re. placement of their ads. E.g. Disney's front page ad for Frozen was bove a story about a "Paedo" & with a woman holding up her tennis skirt so you could see her backside - so maybe advertisers pulling out wasn't irrelevant to this campaign. Disney had responded to a NMP3 campaigner by saying they'd be more diligent in future about where their product name was going to be placed.
Cbeebies & Cbeebies Land were quite happy to advertise with a paper that had a "mark of the devil" on their front page though. 
This is beyond Page 3 for me - but about the new brand image too. The Sun has to decide if it's a family friendly, "we say who gets to be Prime Minister" paper - or we're a paper where the Head of PR mocks politicians on twitter and don't give a fuck about any of it. Remember this is the paper in the same family as Fox News who spectacularly don't give a toss about the truth.
And all this has happened in the week when the verdicts on the (latest) corruption trial (involving Sun journos) were due to be announced.
