If the press were to follow the same rules as broadcasters, it would die and we would have nowhere near as much investigative journalism as we do now.
The press is dying already, and let's be honest, we don't have much actual investigative journalism from the press anymore. Website requirements and 30 minute deadlines before publishing a story, as well as losing money hand over fist, are putting pay to that. The broadcasting industry is where you see much more in the way of actual investigative journalism, usually in current affairs documentaries. Heck, I think requiring newspapers to work under the same rules as broadcasters, might actually give the press some actual credibility again, and might save it, or at least slow its death throws down.
Although Carole Cadwalladr has been doing great work for investigative journalism in the press over the last couple of years, perhaps more free to do so without the shackles of supposed "impartiality" within broadcasting.
I don't think any of us here though are saying the press should be impartial - let's just start with them being truthful.
Nobody is truly impartial, not even the BBC, and nobody ever can be. What passes for it these days is sometimes refered to objectivity, meaning you present two sides of a story all the time, even if one side is always made out of facts, and the other is always fiction. I hardly call that objective. Even worse is when they put out a pound of official propaganda, and then present an ounce of counterspin. That isn't really objective either. True journalism isn't about objecticity, it's about skepticism. Not skepticism to the point of conspiracy theory, but useful, honest skepticism. Present the facts, compare it to what's being said by politicians, and then go from there.
I'd like to see some factual reporting from the press these days, I'd like to see them call out politicians of all affiliations when the facts and the spin don't match up, but most of the press is in bed with one party or another (but mostly one party), and are so blindingly loyal to that party, that they don't even question it when their own side is lying to them. That's what needs to end, this idea of blind loyalty to a party or ideology.
