Is Stereophile seeking a new reader demographic?

If I want to read about political events and topics, I will buy Time or Newsweek, not Stereophile. Sure the two can exist in a magazine, but so can porn or some other subject that is just not what most of us signed up for. IMO, the space that is employed by Stereophile writers giving life to their political slant should be about audio.
Not for anything, maybe I am naive, but has anyone ever seen a TV commercial for Mark Levinson, Audio Research, conrad-johnson, etc,etc. Has anyone ever heard them advertise over the radio. Has anyone ever had a pop up on their computer form any audio manufacturer. The medium is there for the audio industry to reach all demographics in the entire world and yet, a few audio magazines are barely breathing trying to carry the weight of the industry in fewer and fewer pages.

is it possible that a more successful business model for stereophile, to expand the topics covered ?

granted, readers will be lost, but perhaps, others will be gained ?

what is sacrosanct about a one-subject magazine ?

Many years ago a collage professor said , to determine where we are going we must first understand where we came from . Rather than trying to reinvent itself with low priced gear , music servers, USB dacs and such , maybe Stereophile should look at the past . The glory days when Larry Archibald and J.G.H. ran the show . That would likely interest new readers more than a bunch of new technologies .
