They may be but you don't have to see them. Are you aware of AdBlock? It used to be free and they may still offer a free dowload.

You may still encounter sites where you have to disable the AdBlock before you can view the site but that's you decision to make. Once you have seen what you want you can enable the AdBlock again.
