Here in Sweden it's illegal to make ads directed at children. Consequently the TV channels that do so transmit from abroad.
This would of course have been easy to ban anyway-- it's not like we can't have rules on foreign internet firms, for example, but historically the politicians were unwilling to make a useful law.
I think the Swiss could take one step further and add a general ban on ads targeting young children in addition to this; and then we Swedes should imitate the package.
