My job is making Gallup polls on the phone. I've had some bad experiences with trying to ask people about their media usage.
Me: We'd like to interview you regarding the media outlets you've used over the last...
Old lady: No no, we don't have anything like that, just the TV and radio for me.
Me: How often do you watch this channel?
Young guy: Really rarely.
Me: 1-4 times a week?
YG: Well, not THAT often! Maybe once a week.
Me: Have you used the Internet within the last month?
Old lady: Um... what is this "Internet" exactly?
