Here's one more example of DoubleClick's unparalleled level of integration with the search engines. MSN has just issued an online collaboration tool called SPOCK, which is exclusively for the purpose of facilitating communication between MSN and DoubleClick. Based on Microsoft's Sharepoint application, SPOCK will facilitate sharing of information about the AdCenter API, product releases, new features, and the like. It allows DoubleClick employees to ask questions and discuss client issues. DoubleClick is the first company to which MSN is making this type of customized application available.
