From the Google blog:
We’re pleased to announce that we’ve acquired the assets of Zenter, a company that provides software for creating online slide presentations.
You’ve heard us talk a lot about using the web to improve group collaboration and information sharing. These days, when you create a document — whether it’s a text document, a spreadsheet, or a presentation — you usually want to share it, collect feedback, or communicate about it in some way. We on the Google Docs & Spreadsheets team focus on making this experience easier and more powerful for you. In particular, we’re working to add presentation-sharing capabilities to Google Docs & Spreadsheets, and we’re excited about the addition of Zenter’s technology and team to that effort.
