May 2010 was a great month for YouTube. Not only did users of Google's online video service stream more videos per month in the U.S. than ever before (14.6 billion), but according to online analytics firm comScore, every single YouTube user now watches more than 100 videos per month. In total, Google's video properties now command slightly more than 43% of the online video market. No other online video service currently owns more than 3.5% of the streaming video market. In total, about 183 million Internet users in the U.S. watched online video last month.

Adobe Systems announced today that its Flash Player 10.1 software for mobile devices is now being released to its platform partners. The plugin-based technology, which allows for a range of interactive elements including video, games and even advertising, is already available for Google Android phones running the latest operating system revision, code-named "Froyo," but technically known as Android version 2.2. This OS now runs on Google's Nexus One and is expected to arrive on other Android phones like the Motorola Droid, Motorola Milestone, HTC Evo, HTC Incredible, HTC Desire and the Samsung Galaxy S.

Adobe has also now shipped Flash Player 10.1 for mobile to its device partners who will then prep the software for launch on Blackberry (RIM), webOS (Palm), Windows Phone 7, LiMo, MeeGo and Symbian smartphones.

The one notable exception to this list is, of course, Apple's iPhone.

When the popular iPhone application for Facebook got a dramatic refresh last summer, lead designer Joe Hewitt said that the inability to view Facebook videos was a real disappointment. This weekend that changed, and Facebook iPhone users now have a very nice experience viewing videos on their mobile devices.

A quiet update to the application on Friday fixed a number of small bugs but the biggest change was the introduction of video. Facebook sees 2 billion video views each month, which is the same number YouTube sees every single day.

Looking to save money on your wireless bill? Have the new iPhone? Maybe you should start making video calls instead. With this week's launch of the new iPhone 4 and its accompanying software, the Apple smartphone now enables a video calling feature by way of a new application called "FaceTime." And apparently, these videos calls, unlike their voice counterparts, are free.

Radvision's Tsahi Levent-Levi, writing for No Jitter, sums up the obstacles for widespread telepresence use in the enterprise: "It costs so much to purchase such a system and make room (literally!) for it and install it, that even large enterprises will only have 1 room per building for it." The situation leads to upper-level executives' needs taking priority to the needs of the rank-and-file. And that leads to lower overall use of the system.

CBS.com is experimenting with HTML5 video, the plugin-free video technology supported by Apple mobile devices including the iPhone and iPad. With HTML5 running on the CBS website's back-end, visitors from these and other Internet-connected devices could stream videos without having to install the Adobe Flash plugin, something that Apple CEO Steve Jobs is known to be vehemently against, having penned a public statement giving half a dozen reasons why Apple mobile devices won't include its support.

According to CBSi's SVP and GM of entertainment, Anthony Soohoo, CBS.com plans to reach HTML5 parity with the plugin-based Flash video, but is still trying to find the right mix of tools in order to do so.

How appropriate that these current tests utilize Star Trek Enterprise episodes for the experiments with this futuristic video technology.

On the heels of a report which found that online ad revenues will likely surpass those of print ads in the next year, television networks are poised to increase the number of ads run during episodes of shows viewed online. Will Richmond of VideoNuze reports that ABC intends to double the amount of advertisements displayed when viewers watch episodes of ABC shows on the network's website after implementing a similar policy for its iPad app.

Last night Microsoft unveiled Kinect, the company's foray into motion activated controls for the XBOX 360 gaming console that was previously known as Project Natal. Users can play games and navigate menus and web apps by waving their hands or by using their voice, but the camera in Kinect can also be used for social communication. Announced this morning at Microsoft's keynote at E3, Xbox Live users will also be able to video chat from their TVs with friends and family using Windows Live Messenger.

The Guggenheim Museum is teaming up with YouTube in partnership with HP to discover the art of YouTube videos. Tasked with uncovering the "most creative video in the world," the companies have launched an international search by way of YouTube Play, a specially branded YouTube channel that will feature the entries in this new competition.

There's a popular, but apparently unfounded, belief that those who watch videos on their mobile devices are mostly teens. This isn't the case, says Nielsen in its latest "Three Screen" quarterly report for the first quarter of 2010. More than half (55%) of the mobile video audience is actually adults, it finds, aged 25-49.

And while mobile video viewing on a smartphone still remains a niche activity in comparison to total audience size, its year-over-year growth (51.2%) is impressive.
