If you are online website owner that uses Google's referral ads via Adsense you'll have to come up with a new way to earn commissions on products. The company announced that they are retiring the program and streamlining it with Doubleclick which they acquired last year.

The Internet giant sent this memo out to users of the service yesterday that read as follows:

Thank you for participating in the AdSense Referrals program. We’re writing to let you know that we will be retiring the AdSense Referrals program during the last week of August. We appreciate your patience during this transition and here are some alternative
options to consider:

* Google Affiliate Network: As part of the integration of DoubleClick, the DoubleClick Performics Affiliate Network will now
operate as the Google Affiliate Network for advertisers targeting users located in the United States. Similar to the AdSense Referrals program, the Google Affiliate Network enables publishers
to apply for advertiser programs and get paid based on advertiser-defined actions instead of clicks or impressions. For further details, please visit:
