Retransmission and Internet revenues can't climb fast enough for TV stations. But in a few years, both will be contributing significantly to stations' coffers. Each revenue source will be over the $1 billion mark, according to two recent estimates.

A joint research repoft by the Cable & Telecommunications Association for Marketing and research firm NeuroFocus found that TV earns high marks for emotional engagement, commercial recall and intent to purchase. Small-screen media is less immersive; as such, viewers tend to find that advertising on mobile and Internet platforms is not nearly as engaging as it is on TV.

While TV broadcasters have the clear edge in online video, they had better establish some sturdy ad formats "while there are still revenues from the traditional business to support the transition to multiplatform," according to new research from media analyst firm Screen Digest.

Analysts say Internet companies and ad agencies have no choice but to work together to develop ways to make money from digital media.

Hollywood studios and television networks lost their bid Monday for the Supreme Court to block the use of a new digital video recorder system that could make it cheaper and easier for viewers to record shows and watch them when they want, without commercials.

Publicis Groupe said Thursday it has reached a multi-tiered deal with Microsoft that includes development of both digital content and a customized online ad exchange.
