Peppa Pig 'is teaching American kids to speak with an English accent'

"A British show for children is allegedly warping American toddlers’ speech toward “Mummy” and “to-mah-to,” according to several parents who have recorded their children speaking with an English inflection. But according to linguistic experts, the Peppa Pig effect, first reported by the parenting website Romper, is less a soft-power victory for anglophilia than a normal toddler tendency to mimic new words.
Peppa Pig, which first aired in 2004, features a town of animals speaking in Britishisms such as “zeh-bra” or “straightaway”. In the Romper post, Janet Manley reported that her two-year-old daughter started calling her Mummy after binge-watching Peppa Pig on a 21-hour trip to Australia.
Other parents have shared similar observations online: “The most entertaining aspect of my life right now is that my toddler has been watching Peppa Pig and now speaks with a British accent,” wrote Twitter user Jess Steinbrenner. NBC Charlotte posted a video of a young girl calling a car “wei-ard” instead of “weird”. Several parents said their kids were pronouncing “tomato” as Peppa would."

Note - The article partly denies the story later one - saying that you learn accepts through interaction, but that the kids may be imitating some words.
