The thing that's changed is the proliferation of noise generators. The RF environment has become so bad that broadcasters have raised the issue with the FCC, and the FCC is studying it in a serious way.

In a tutorial/applications note about finding and killing it, I made an educated guess that the average residence has at least two dozen, and probably three dozen, HF noise sources.
