What will be the next "big thing" in direct marketing?

The next big thing will be Direct Marketing by request.

How?
By the development of interfaces that will allow customers to request more information about a product or service when they see an ad commercial on TV or on another media channel.

To visualize what I’m describing, I’ll give you an example:
Imagine that you are in your living room watching TV, commercials are on, and you see an ad about a product or service that you are interested in.
You will be able to request to be contacted immediately about that product or service by a click in your remote control.
The contact will be made or by video call through your TV, or through your phone if you are pre-registered in this service.
