I suspect that the distinction is on its way out, here in South
Africa. We were never 'little England' in the way that New Zealand and parts of Canada were, but we only got TV in about 1975, so American influence was limited to cinema and
Elvis etc on the hit parade! Now, there's immense amounts of American soapies, series, made-for-TV stuff that probably wouldn't survive in a cinema ... and it's showing in our naming habits, though since we don't have access to annual naming records, it's hard to quantify.
