Maybe El Comercio is just trying to copy what The Daily Mail is currently doing, which is to dumb down for the masses.
The Daily Mail has always been a little bit of a right sided mid-low quality paper (think if Fox news were a paper)that believes it is better than what it actually is. Yes it does give proper news stories, but it never covers the stories as well as the more upper class papers. It's seen the rise of it's webpage growth by basically ripping off The Sun (biggest rival and a trash paper which it hated) and just filling it's pages with half naked celebrities and celebrity gossip, which is what sold copies for the Sun.
It does it's best to avoid being as trashy by not showing topless naked shots of the stars and using words like "pert" and "derriere", but everyone can tell it has just sold out.
Maybe this is the path El Comercio is trying to follow?
