In short, scientists conclude that "TV does seem to meet the criteria for substance dependence."1

Your scientists have done studies with people connected to an EEG brain-scanning device while watching TV; they registered activity in the delta wave frequencies, essentially occupying a highly programmable sleep state while viewing TV.

Abnormalities in brain function have traditionally been detected using electroencephalography (EEG), which involves the measurement of the ongoing electrical activity generated by the brain.
