The primary usage is in medical equipment, not terribly sure why you would need or want one for old TVs and radios...
MEG and EEG equipment is commonly connected to line-isolating equipment, and there are numerous fail-safes in place within the circuitry of equipment itself that keep an EEG from becoming an unexpected trip to the electric chair. The risk with MEG is minimal as you're essentially wearing an enormous dewar on your head and there's no electrical contact to begin with. EEG there's a real risk if strict isolation of the leads and amplifiers from the power supply isn't maintained at all times. The same goes for EKG equipment...
It also helps keep the noise and BS from Edison out of the power supply, which is a great advantage when trying to amplify such incredibly small signals.
