in short:
The August 28, 2006 press release about the agreement (linked above) says, in part: “Google Inc. (Nasdaq: GOOG) and eBay Inc. (Nasdaq: EBAY) today announced a multi-year agreement to benefit both companies’ collective communities of users, merchants, and advertisers around the globe. The agreement consists of two primary components involving text-based advertising and “click-to-call” advertising functionality.”
The press release continues: “Specifically, Google will become the exclusive text-based advertising provider for eBay outside the United States. In addition, eBay and Google plan to integrate and launch “click-to-call” advertising functionality that leverage both Skype and Google Talk globally in each company’s respective shopping and search platforms. The companies said the financial terms for certain components of the deal involve revenue sharing, but did not disclose specific details.
