Amazon Prepares Online Advertising Program

If Amazon took away 10% of what Google's adsense business 4 years from now would have been that is likely material to Google's earning. Not huge but real.
Even losing the ads on Amazon's web site is likely noticeable (though not a huge deal I would guess).
There is even the potential Google has to reduce their profitability to compete - giving web sites a better cut of revenue.
That said I think Amazon has plenty of challenges to making it an effective competitor to Google. But they have a chance. And there is even a small chance (very small I think) that Amazon could create a competitor that actually results in noticeably (say over 15%) declining revenue to Google via adsense. Likely even in this case Google continues to grow profit.
Google revenue from ads from their own websites are the most important earnings and likely to continue to be so. Also new business (non web-ad-income) is growing and I think will continue to do so (this is likely an area some might find more questionable).
And as far as people doing product searches on Amazon.com, it's not a great source of revenue for advertisers. If you want to get real sales from Amazon customer searches you need to have your products for sale either via Amazon itself or in the Amazon marketplace. They make way more money that way and place the way they place ads on their pages reflect that.
Google will retain total dominance in this area as long as a the vast majority of people use google.com for web searches.
Ok, But no one asked if it will work or not. And your comment doesn't have any extraordinary analysis or information that someone with even a small understanding of the topic wouldn't know.
Maybe even more importantly, they know which products you returned and why. Public reviews on items are one thing and likely gameable, the direct merchant feedback form remains private between the merchant and the customer. And Amazon, of course, because they mediate the exchange.
For pure marketing purposes that kind of limited view could be quite valuable indeed.
As to what this means for me? More rules in AdBlock, I guess.
