Good point. Though, I think that really works with physical goods. It definitely works with services (pointing at the massive box billboards) but online is still where you engage the service and the offline presence may become less and less relevant/necessary as more and more of your time is spent online.

It works with all products. Haven't you seen the Angry Birds billboards, TV ads, etc? Or the Google Chrome campaign? Or maybe the avalanche of shoppers that walmart sends to customers both online and offline.

Digital products still have a need to advertise offline in the same manner as physical products. Nowdays, it makes more sense to also market offline because fewer people do it.

I'm not saying it doesn't work - just not sure it will remain as effective as it is today or as it was 5 years ago. I think the effectiveness will die down over the next few years.

Repetition is definitely how ads succeed (convert). That said, being both offline and online is good (as you say). However, if more and more of your time is spent online (or a given company's target user's time), doesn't it make sense to create more repetition online? Through different online mediums? Search, display, retargeting (talk about repetition)...
