Recently-formed media agency Assembly says it will use YuMe’s new Reach Calculator tool, developed with Nielsen, to show advertisers the effect of moving ad spend from TV to online.

“Being able to play with it with the client sitting at our desk is something I’m excited about trying,” says Assembly’s group planning director David Klein.”

“We know the concept of adding a new media channel in to our mix is going to add reach in to our plan. But having the ability to break it out between the different channels and screens is an essential piece for us. Traditional brands are slower at making that move.”
