I've noticed this more in Belgium Flanders. A region of a postage stamp country compared to the US where accents/dialects often weren't even fully mutually intelligible over distances that weren't so great. This homogenization was first pushed trough education and such but it remained among the more rural folk (in as far as rural exists in such a densely populated region) but now media and migration are rapidly killing it off.
