Hi,
FWIW I've never thought of any of the tabloids as newspapers, as there's never any actual news that they would print, solely because it would be deemed too "complex" for their average readers. If the story can't be condensed into sentences of less than 10 words, and one paragraph, then you won't find it in The Sun, or any other red-top wrag!
In all seriousness though, alll media outlets (print, audio, visual or Net) have their own slant to push, be it political, social or something else. Even "The Independent" is not truly equal in the stories it publishes, but at least it tries to maintain some integrity and stick to a neutral ground. The web can also be just as biased, depending on which site it appears on. And, in all honesty, any site that printed just nothing but facts, would find there isn't much of a "story" to be made.
An easy, and obvious example is the recent story about Madeline McCann (sp?). From Day 1, there's not really been a story to tell. The only actual facts are as follows:
- older child was left with two younger siblings, whilst parents went out
- parents checked on kids every half-hour or so
- elder child goes AWOL, presumed kidnapped
- hunt continues for missing elder child
That's it! That's not a story, though. It's just hard facts, with no substance to it.

If that's all you want, it's easy enough to pick out from the various versions of a story (TV, radio, press, etc), what the actual facts are. The rest is just journalistic second-guessing, thoughts and opinions - which are all the parts that make-up the rest of the piece, and end-up becoming the "story" that gets printed or spoken about.
I guess the bigger problem, though, is the fact that the tabloids don't even print stories now, but just opinions and material that's as close to slander as you can legally get. There's not a single ounce of "news" in anything they publish. Even headlines are questions and opinions, or attention-grabbing self-congratulatory slaps-on-the-back e.g. Serial Killer caught, thanks to your Daily Mail, etc, etc.
Sadly, it's this kind of parasitic bile, that the average person is happy to shell 45p (or whatever) to read, and stay "informed" with what's happening in the world.

But it's not genuine news!
And, if the story's published in The Sun, then it absolutely must be the truth, mustn't it?!
Pooch
