Google of Mountain View, California, said closely held dMarc connects advertisers to radio stations through an automated advertising platform. Google said it expects to integrate dMarc technology into the Google AdWords platform to create a new radio ad distribution channel for Google advertisers.
I really don't see any conflict. The primary offering on their site is search and always will be. That's what they grew on, and then with offering advertising acquired a huge customer base. There's just so far they can go on that, and what it looks like now is that they're starting with the original commercial advert offering and expanding more toward functioning as a multi-channel media company.
Those really are two completely separate areas of operation, the search and the commercial operations, and there's no reason why they can't both function independently of each other.
Here's an interesting perspective on what appear to be Google's moves toward what's traditionally been agency work
Can someone remind me how Google got their start? Didn't it have something to do with that internet thing?
Understandable concern. One might wonder if Google is getting spread a little thin. But Google, like Yahoo, et. al., isn't into "the internet". They're into "information" -- organizing it, selling it, serving ads that are related to it (not just "information", but, the information YOU are looking at/for) and so on. If you can build a self-service advertising platform like Adsense or Overture for the internet, why not for radio (or TV) advertising, too (particularly if you can target very specific markets/demographics)?
