Google's vice president of engineering, Vic Gundotra welcomes the 5,000 attendees, notes that the keynote is being streamed live on YouTube for the first time, and offers a concise definition of Google's mission: "Innovation in the Open." He elaborated briefly on the web openness and as the most important platform which belongs to all.
Sundar Pichai VP of product management update about the Web's development language that should allow far more desktop-like Web applications. He quoted a 117 percent increase in the time spent on the Web from 2004 to 2009 and the growing number of browsers that can handle most of HTML5's core features. He compared various browser support ( Internet Explorer, Firefox, Chrome, Safari, Opera ) for HTML5 and predicts that by the end of the year, "all of the major APIs [application programming interfaces] will be present in all the modern browsers."

Pichai announced the VP8 video format ( bought from On2 Technologies ) to the Web. It will be a fully open-source VP8 under a completely royalty-free license. Google will package it with the open-source audio format Ogg Vorbis as "WebM." Mozilla's VP of Engineering Mike Shaver and Opera's CTO Hakon Lie demo how WebM works in development versions of their browsers.

Adobe CTO Kevin Lynch elaborated on what the company is doing to support HTML5 in its Web-authoring tools. He demo apps like DreamWeaver which allow one to build HTML5 pages. By so doing, one need not rely on a third-party plug-in to play video online which imposes extra maintenance work on the user to keep up with that plug-in's bug fixes and security patches. Second, leaving Web video as a proprietary format goes against how the rest of the Web works--no patents or licenses control HTML. Third, a format that requires that Web developers and publishers pay to use it can hold back the growth of video ( example H.264 is free through 2015 ). With this given free, Google is trying to solve those problems--which, if it causes more people to spend more time online, can only help Google's ad business. Lynch wraps up his demo by saying that the Flash Player will play VP8 video--which gets around IE not supporting VP8 directly.

Pichai offers a solution to finding apps on the web : he introduced the Chrome Web Store. Chrome will add an app store of its own, allowing one to buy a Web application and add it to a special listing of apps in the browser. This service will also allow developers to sell their apps in an online market. He demos 2 apps Plant n Zombies and Web-app version of Lego Star Wars , both were good of what HTML5 can make possible. Even if it is called the Chrome Web Store, these apps, Google says, will be usable by anybody that has a computer and a web browser at their disposal. They won’t be restricted to Google Chrome.

Presentation by Terry McDonald , Editor of Sports Illustrated showing off an HTML5-enriched version of the magazine obtained from the Chrome Store that embeds video, bookmark features of stories and clips, uses the magazine's own fonts, search functions and looks exactly like the printed product.

Pichai present more features about Chrome Store. He says app developers can reach 70-million users of Chrome, who will see this waiting in that browser's new-tab page. Google's upcoming Chrome OS software for netbooks will include the Store too. And since Chrome apps rely on Web standards, they should work in every other modern Web browser.
Lars Rasmuse present Google Wave, the info-sharing/messaging/collaborative-creativity system Google launched at last year's I/O. It is now free and is part of Google Apps, its bundle of productivity applications.
