Salesforce.com and Google are expected to launch a combined Web site today (dated June 5th 2007) that is designed to allow the online customer relationship management software maker to act as a reseller for Google's AdWords.
So Google allows you to insert ads into your video stream now (it's already in beta!). The customers that want their ads published will be maintained in this online CRM tool developed by Salesforce.com. This will be mostly targeted to small and mid companies.
