Back in 06 when eBay announced the launch of their own affiliate linking infrastructure called Project Rover, Shawn Collins and others wondered if that move signaled the beginning of the end for the CJ eBay relationship.
Shawn gave me a nudge today to let me know that eBay just announced they will indeed be closing their CJ affiliate program.
The eBay Partner Network officially launches on April 1st, 2008 and will run in parallel with the Commission Junction program for one month to give affiliates a chance to change out all their links. So you need complete your migration by May 1st, when the CJ program closes.
Shawn has a detailed story, including quotes from CJ and eBay, so head over there to get the full scoop.
