The 4 big trends affecting the media industry today

[Commentary] 1. Presidential election hangover: Advertising revenue comparisons can often be a drag on earnings, but nothing stings quite like a quarter that has to stack up with a presidential election, particularly one as contentious as the 2016 race.

2. Mobile future: It might be hard for programmers to continue to grow their affiliate revenue. But Viacom CEO Bob Bakish sees mobile content as a potential growth driver in the future.

3. Retransmission express: The retransmission revenue train just keeps on chugging along.

4. ATSC 3.0: All systems go: Should the retrans express ever go off the rails, broadcasters will have a number of new revenue opportunities now that ATSC 3.0 is officially off the ground.
