Oh, 100% agreed there. But in a a larger conversation about "the media", Dominos is analogous to a large, mass-market, low cost outlet, not the media in general. It's entirely possible that TMZ or People Magazine had similar improvements that still keep them below the radar of someone serious about the product.
So yeah, some credit, that's fair. But I think the lesson is that good management recognizes when quality is falling off the bottom of the bottom rung, and makes adjustments to get back on that bottom rung.
