Brazil has 213M inhabitants. Portugal has 10M, the population of the municipality of São Paulo. So, Brazil is the biggest Portuguese speaking country. Portugal has a higher per capita income, but there are at least 60M Brazilians who have income similar to the Portuguese one. So, most of the Portuguese speaking content in the Internet is in Brazilian Portuguese and not European Portuguese.
An article in a Portuguese newspaper told that the Portuguese parents are worried because due to the Covid restrictions, their children stayed at home watching Youtube videos produced by Brazilians. They started to speak like the Brazilians: speaking "grama" instead of "relva" (for grass), "ônibus" instead of "autocarro" (for bus), "geladeira" instead of "frigorífico" (for refrigerator).
A Portuguese teacher told this concern is not new. There was already influence of Brazilian Portuguese in Portugal through the TV soap operas. There were also the Walt Disney comics, whose translation in Portuguese was done in Brazilian Portuguese.
