Have you ever loaded up google, searched for something, like, "How many types of socks exist," click on a site, and not find what you're looking for because of all the ads? I have. With some sites, even, there will only be 1 small paragraph, but it is impossible to find because of all the ads!! Well, I know companies are just wanting to get their product sold, I think the websites themselves should take charge. Even with kidzsearch, there are moving video ads that try to distract you. As I'm writing this, I see a lipstick ad for 'The Mature Woman"!
Now, what if a 7-year-old is doing research for a school project, not knowing that the site he clicked on has some VERY inappropriate ads for their age group. When people see moving ads, it immediately distracts them from what they're looking for. This is very inconvenient, especially if you are researching for a project that has a deadline, and get distracted by a video ad for a product you 'need.'
