Addiction is usually linked to substance abuse or similar. Other forms of "addiction" are difficult to cleanly disentangle from people simply liking things for their own reasons, acting on their own free will. That's how you get things like TV being described as "addictive" though I never heard of anyone going into prostitution so they could afford their cable bill. Perhaps there are stories of it happening somewhere, but such a story would be rare and shocking, whereas prostitution for feeding a drug habit is unremarkable. But let me turn it around. How do you define it? Above I've seen people claim that anything that has advertising in it must by nature be "addictive" but that would cover 20th century newspapers, and again, I never heard anyone describe them as addictive or display uncontrollable cravings for newspapers.
