ISPs Owned By...Power Companies?

Jkior asks: "I've been using a local ISP - no problems for over a year and excellent service. Recently, however, they were bought out by a regional electric company. Which started me wondering - considering the GB/S or so bandwidth planned by MediaFusion, using the power lines. Is this happening anywhere else? Could power companies be seeing the possibilities in this?" MediaFusion's basic plan is to use the magnetic field surrounding the powerline as a communications medium as opposed to voltage or amplitude modulation. Since power lines connect more people than even phone and cable, might the beginnings of a true broadband global network be right around the corner?
