After a debut in May that limited access to X1 subs, Comcast said all customers can now tap into Xfinity Share, the company’s new live streaming app that shares some similarities with Meerkat and Periscope.

The move vastly broadens the availability of Xfinity Share, which uses  WebRTC, an open Internet standard that supports real-time communication via Web browsers.

Update: All Comcast subs can now use Xfinity Share on mobile devices  (the app is offered on iOS and Android, and the new 3.0 version enables users to record live streams), and they can use the platform to send photos or videos to the TV, though the latter group will need Comcast's  X1 service (with a DVR) to watch the stream or receive photos and videos on the TV. Xfinity Share currently lets customers share content on a one-to-one basis, but has plans to let customers send content to up to five people at the same time. 

“Starting today, every Xfinity customer - video, Internet, voice, and home - can use Xfinity Share to live stream and send photos and videos to a TV,” Patti Loyack, vice president of communications at Comcast Cable, said  in this blog post. “They can also use the app to send or receive live streams, photos, and videos on a mobile device. To watch live streams or receive photos and videos from Xfinity Share on the TV, consumers will still need to have X1 DVR capable set-top boxes.”

While Xfinity Share shares mobile traits with Periscope and Meerkat, Comcast bills it as the first live streaming app that lets users deliver that content directly to the TV.

Loyack noted that the spring debut limited access to a smaller subset of customers so Comcast could learn how people were using it.

“So far, our data has shown a huge uptick in Xfinity Share usage on weekends and holidays when people are more likely to share big events – weddings, vacations, and graduations – that deserve to be viewed on the big screen. Plus, the majority of people who tried Xfinity Share are repeat users,” she noted.  “By expanding the number of eligible users to the millions, we can’t wait to see how people will use it next. We’re also working on adding new features that will make the overall Xfinity Share experience even better.”

Comcast hasn’t released more detailed usage figures. According to Google Play, the Xfinity Share app has been installed between 50,000 and 100,000 times. 

Who needs the upfronts, with their professional comedians and fancy clips and trailers? For the finance set, there was plenty of funny going on at what is becoming one of the hottest tickets among people who generally have to search for humor deep within EBITDA and OIBDA results, the MoffettNathanson Media & Communications Summit in New York.

Although not open to the media, presentations at the standing room only conference were streamed live on the Internet by most of the companies – at least the publicly traded ones – and sprinkled among the boiler plate were a few comic gems from the likes of Comcast chairman and CEO Brian Roberts, Charter Communications CEO Tom Rutledge, Time Warner Cable chairman and CEO Rob Marcus, and AMC Networks CEO Josh Sapan.

While nobody is suggesting any of this group quit their day jobs, here’s a sampling of some of their more humorous asides.

• Josh Sapan on his first encounter with streaming live video service Meerkat:

“I downloaded Meerkat and was pressing buttons like the old guy I am, and I kept looking up at my phone and it kept saying, ‘Stiletto Supermom is live now.’ I kid you not. Finally my wife looked at my phone and said ‘What’s with you?’ Stiletto Supermom turned out to be a mother with her daughter cooking dinner. We actually decided to push the button and check out the transmission on Meerkat and it was very benign. It was, frankly, ferociously boring.”

• Brian Roberts on the first time he and now-NBC Universal chief Steve Burke called on former Viacom CEO Mel Karmazin to discuss a deal for the fledgling technology of On Demand:

“We were there to get 60 Minutes and Mel said, ‘I’m going to put my head down on my desk and cover my eyes and count to 10 and when I’m done, I want you two guys gone.’”

• Rob Marcus on whether, in light of the termination of the Comcast merger and consolidation speculation, he had any news to share:

“What did Rutledge say?”

• Brian Roberts on being told by Bill Gates in 1997, just before the Microsoft founder invested $1 billion in Comcast, that one day Internet customers would exceed video customers.

“I didn’t know what he was talking about, but I was happy to take the $1 billion.”

• Tom Rutledge on the notion that FCC chairman Tom Wheeler isn’t too enamored with cable’s broadband success:

“What are you going to do? You’re selling stuff and people are buying it. You should keep doing that.”
