Cross channel advertising

Why I am seeing the same single ad using dailymotiom and youtube. Is it interoperability which is one of the core components of systems that allows adaptability and extension? Is it the sharing of personal information between platforms? Cross channel advertising is this thing that want to jnteract with yiu in differrent places. This is something interupt marketers believe thst this gonna be improving their results but if it doesn’t interest you in the first place how will it be the others.
I got a cross channel targeting system and still won’t do interruption marketing. My trouble is to know how can I do permission marketing with this highly populated channels I had found? This permission marketing will be more effective if I use MVA like this
