Anyway...To get back on topic.
I think the TV method is a very effective marketing tool. We don't play the sound from the videos because we have music playing in the shop. They are just playing on the TV, and a surprising number of customers become quite engaged by it. They really had no idea what real pizza is, so this is very educational for them.
I'm not such a fan of things that require people to read. People don't like to do that. If it's longer than 147 characters, they get distracted.
