Charter Communications, Cox Communications and Comcast, which collectively own a cross-screen media sales company called NCC Media, are creating a new division within NCC to design, sell and deploy ads across the data networks of the three companies. The companies said Wednesday that they will launch the division later this year.

Why it matters: Data-based ad sales is the future of advertising. They are more cost-efficient and can better target individuals, increasing the likelihood that the ads are more receptive and; therefore, effective, for users. TV networks and digital websites are similarly forming these types of combined networks to sell ads, because the larger your footprint, the stronger your data sets are.
