My comment might not have been clear. I didn't mean to infer ads. In my mind there's a clear and distinct delineation between advertising and marketing.
I guess the point I was trying to make is that the kinds of marketing that companies want these days is going to be far more immersive than your run of the mill ads. This, I think, was one of the main points of the parent comment. As such, I would postulate that the skillset necessary to write a good article, or in-depth (eg. investigative journalism) story, is very similar to the skillset necessary to create (or find?) the stories a company wants people to know about it.
Now, the tricky part would be to engage in both journalism and marketing so as not to uproot the integrity (or give people reason to think your integrity as a news organization has been compromised, or that you are engaging in business with clients who clearly create a conflict of interest.
For example, suppose you are a newspaper / magazine who has a reputation as being a "watchdog" publication for the oil industry. Now suppose that while that branch of your business has established a reputation as a "watchdog" publication for the oil industry, the marketing arm of your business has clients like Exxon or Shell. To maintain the integrity of your journalism branch perhaps you should be working with clients seeking marketing services from other (eg. retail) industries.
The only reason this synergy sounds reasonable and even plausible to me is the well documented "crisis" news organizations worldwide are facing these days.
