One of the first appearances of a mobile phone in a major Hollywood movie was in director Billy Wilder's 1954 Audrey Hepburn classic, "Sabrina". Today, millions of phone owners across the world could recreate "Sabrina" from start to finish from the comfort of their hand held devices. In fact, if we chose to, we could mobilize a global streaming event. But let's be honest, the last thing we want to do is sit inside story boarding a pre-existing movie. It's the summer! Get outside, grab your phone and capture some of the great moments happening around you. Below are some of our favorite mobile video services.

In the early hours of the morning, Commander Mark Polansky sat watching the Tour de France when he got the call that they'd be fueling NASA Endeavour's external tank. Nearly 30,000 of his Twitter followers woke up and rejoiced at the news. Today we're going to see lift off.

The NASA Endeavour was set to launch to the International Space Station today at 7:13PM EDT from Cape Canaveral, Florida after a 24 hour lightning-induced delay. The mission was delayed several times and while Commander Mark Polansky's Twitter account and NASA's official account announced that the launch was likely to happen, online viewers watched via NASA TV as the mission was scrubbed with only minutes to spare. The launch has been rescheduled for 6:51PM EDT tomorrow.

Twubs - it's not the mean-spirited nickname the kids called us in high school, nor is it the Miami Vice detective opposite Don Johnson. Similar to Hashtags.org, Twubs is a Twitter aggregator that allows users to contribute on breaking news, popular trends, shared conferences and memes such as #followfriday and #musicmonday. In addition to indexing basic tweets, the service also displays photos and videos that share a common hashtag. Earlier today Twubs launched a free conference suite in the hopes that conference planners will take a cue from Gnomedex founder Chris Pirillo and incorporate back channels and live feeds into their events.

Ustream, the live video streaming service that hit the mainstream recently thanks to a litter of Shiba Inu puppies, just announced Watershed, a new white-label streaming video service. Watershed features pay-as-you-go pricing, high-definition video, and extensive options to customize the viewers' experience.

Forget the implosion of the housing market. Never mind whether the Big Three automakers have been dragging their heels on fuel efficiency and innovation. Set aside financial deregulation and a culture of greed. I now know the real reason for the economic collapse:

It's those damn puppies.

Reports were flooding in this week over Twitter, about workplace after workplace where people couldn't get a thing done because they were entranced by the antics of those little furballs. Productivity must have gone through the floor since that Ustream channel went live.

Live video broadcasting service Ustream.tv will announce tomorrow that live feeds on the company's website and distributed video players got a combined 10 million unique viewers last month. If those numbers are solid, it's a major validation of live streaming video on the web.

When YouTube Live launches later this year, this medium is only going to get bigger.
