Hi Ziv. Thanks for your comment. I believe that consumers will have to decide for themselves if proactive ads are too much of a nuisance. In terms of pay per purchase vs. pay per impression ads, I believe we will see both, just as we do in other media. Big brand advertisers (e.g. Coca Cola) don’t buy ads on a per purchase basis. And if there’s enough demand from brand advertisers, the device companies won’t have to sell ads on a per purchase basis.
