Microsoft announced it has closed its analytics program - adCenter Analytics beta - and at the end of the year all current users will no longer have access to the program.
Microsoft is recommending that all current users download all their information prior to the December 31 closing. The adCenter Analytics blog stated this program was a success and gave them insight into the analytics process.
"It enabled us to confidently determine that we can be of most value to advertisers and publishers by offering a tailored solution that meets more specialized needs."
Guess they plan on offering an alternative some time in the future.
