I'm sorry, but this is just patently false. 1) There are still plenty of stay-at-home moms and dads out there, or they'd just program the test pattern during the day. 2) Even more people have DVRs, VCRs, or some such device that allows them to watch every day (how do you think I do it?)
Certainly there are plenty of people at home, though it isn't an "either/or" situation: the numbers have decreased over time when examined over decades. Be they stay-at-home parents, workers on non-traditional shifts/schedules, work-at-home types, students, etc. Some of those latter groups might be "regular" viewers in the more modern definition of "regular," being 2-3 day a week viewers.
Of course, coupled with more ways to watch Price (or any other currently programmed "linear" TV show), there are the Netflix services of the world, "on demand," smart TVs with the ability to access internet content, and on it goes. Any program today operates in a radically different landscape than just 10 years ago, let alone 20, 30 or 40. That necessitates doing things differently, and to Price's credit, they've rolled with the times to, as someone so well stated it, make it accessible. It has the familiar elements, but packaged in a way that works well for newer audiences overall. That's a darned hard thing to pull off particularly in "mid-stream" so to speak, and they deserve props for that.
