mathanxiety , an interesting question.
I am all for the content of the press being driven by consumer demand (though of course we must accept that this argument also applies to pornography, for example).
If consumers are demanding that they do not want articles containing sentiments such as the ones in Moir's article, then it would be a very poor business decision for the Mail to ignore this.
However, my instinct is that they will be very very careful about insigating any drastic changes. Remember this whole furore has only taken place over a matter of days.
For instance, what portion of the Mail's regular readership was upset by he article? Not the people who were directed there by Brooker or a website, but the people who buy and read the Daily Mail?
I suspect that a number of these people are actually in sympathy with Moir's argument. After all - as we have already touched upon - her remit is to appeal to the target audience of the paper's circulation.
The Mail won't really have that much interest in appeasing liberal Guardian readers who only ever look at the Mail to sneer at it. Their interest lies in giving their readers what they think they want. This is perhaps true of the Mail more than any other paper, who have always based their output on a reflection of public feeling rather than attempting to shape it.
Additionally, PR companies follow the money. They're not in the game of denying their clients profits in order to follow a worthy moral crusade.
Maybe they do think that the Moir affair is The End for the Mail and no-one at all will ever read it again, but I doubt it.
If the Mail continues to have a large circulation then it will continue to be an attractive space for companies to advertise.
I'd be very supprised if - on the basis of the Moir article alone - any permanant or significant changes are implimented within the Mail.
