Google ad became big, television and news papers advertisement became small. The reasons were very obvious.
Google don't need to follow local law and regulations.
Google don't need to employ people to verify content or take legal responsibility.
Google can track users and thus categorize users in much more fine details than television and news papers ever could. A magazine about horseback riding might have a vague idea about who their readers are, but google can find out that a pregnant teenage girl has yet to tell her parents.
I think the biggest difference is simply a reduction in the relative amount of time watching TV. People see Google’s Ads at work, at home, and while waiting at line looking at their cellphones.
