Despite the fact that change can be hard, Google’s retirement of DoubleClick Sales Manager (DSM) is a blessing in disguise for publishers. The internet advertising powerhouse is focused on their profitable products such as DoubleClick for Publishers, AdX, AdWords, etc. DSM’s sales management and booking workflow tools were simply not generating enough profit, so Google’s options were to invest in the product or cut it. And cut it they did. As of July 31, 2019, DSM will be removed from service.
