Moreover, it may help to make fun of the ads they still see. (on websites, outside at walls, etc.) This may improve their awareness, and hopefully later their critical thinking.
BTW, when I started not to watch TV anymore, I expected that I would miss something, but I didn't miss anything at all!
Friends told me about the few cool series I missed, and I simply bought the DVDs. It is a huge increase in comfort, watching those at my own pace, in their original length rather than the blown-up-with-ads length.
Otherwise, they watch Australua's State run kids channel, which sounds awful but actually tends to run somewhat subversive shows like Yoohoo and Friends (universally panned by those who watched the original Korean version, but not by me or my kids!) and Adventure Time. And not a single advertisement, except promos.
Still have to find something for my daughter, who also loves those shows and we encourage her to watch them, but she is still into Shopkins (despite my best efforts of discouraging her) and other shows designed to appeal to her and her friends.
But she said watches absolutely no commercial TV. This is more by happy accident than design, because commercial TV in Australia is so completely rubbish that there is literally no need to watch it - ever!
I can vividly picture the "Where did my show go??" moment :)
Example: the Disneyland 60th Anniversary TV Special. Disney/ABC is particularly fond of advertising cross-medium Disney properties/investments on Disney-controlled television and radio broadcasts. For instance, Radio Disney definitely plays a disproportionately high number of DMG (Walt Disney Records + Hollywood Records/DMG Nashville) recordings.
My spouse was watching it. I saw 30 seconds of it and said, "this is a long format ad for Disney parks," before tuning it out.
The long-format ads are rather common on the local news broadcasts. Some stations show more than others.
Consumption of advertisements should have age restrictions similar to cigarettes.
We haven't had cable/etc since 2005 and there was a period between '07 through maybe '13 where out kids weren't exposed to any TV commercials except for while visiting grandparents during holidays. The few commercials they saw over the years left a terrifyingly strong impression and desire for those products; they'd remember many, many months later. We still don't have cable, but unfortunately the expansion of content available on AppleTV has meant commercials jammed into everything. Contemplating returning to Netflix disc-only service and ending subscriptions to streamed content.
