Ask pretty much any Croatian who was a kid in the 90ies and they will probably say that watching Cartoon Network as a kid on their satellite dish helped them learn English. Only 3-4 national channels were available on the terrestrial TV at the time, which made the huge variety of satellite channels novel and exciting for a kid. These foreign stations didn't have subtitles, so you had to try and pick up the language to follow the shows.
Children learn language at the same time they are learning how to be little humans. Neurological connections are being forged, deep pathways for life. Watching my son go through that hyper growth stage was mind blowing. He's trilingual. His recall and attention to details is remarkable. In contrast I've got my head in the (internet) clouds.
So no, I don't think we ever have that same level of growth and rapid learning.
