I don't think people have a good grasp of the scale of offset printing. You hear about digital all the time, but it is a tiny tiny fraction of total production capacity. It's like the people who think a car wreck is more likely to kill them than a heart attack because that's all they hear about in the news.
Here's a great graphic that compares Sheefed, Heatset Web, Coldset web, digital and inkjet. Digital and inkjet barely register on the same scale as any of these. And of course, offset printing is the sum of sheetfed and web.
