From the YouTube Help Forum:
“We've seen some of you wondering what occurred to the Realtime Toolbar. The Realtime Toolbar was recently retired and is no longer an available feature on YouTube."
“We were excited to release and experiment with Realtime and it has inspired us for new features on YouTube in the future. We look forward to introducing many new features in the coming months and are sharing them with you all. Many thanks to those of you who used Realtime and for your feedback to us on this feature- your suggestions and input help the Team shape the site and determine what should be developed to further improve the YouTube community."
