DISCOVERY DIGITAL NETWORKS' "DNEWS" REACHES ONE MILLION YOUTUBE SUBSCRIBER MILESTONE

- TestTube Original Joins The Philip DeFranco Show & SourceFed Among Top DDN Series -

San Francisco, Calif. - Discovery Digital Networks announces today that DNews is its latest original series to reach one million subscribers on YouTube. Launched in December 2012, TestTube's DNews ventures into the awesome world of science and explains the curious occurrences in our everyday lives - covering everything from being physically scared to death to the logistics of time travel to the awkwardness of eye contact.

Averaging more than 13 million views across platforms each month, DNews is hosted by Trace Dominguez and Tara Long who are at the center of a winning formula that combines science, smarts and a dose of humor to look at topics that are grabbing headlines or bound to make you scratch your head. DNews continues in Discovery's tradition of providing engaging coverage and analysis of developments in technology and the sciences through DiscoveryNews.com, which debuted in 1998 and seven years before YouTube debuted.

DNews is at the center of Discovery Digital Networks' suite of original programming, which comprises nearly two-thirds of its monthly views across networks and platforms. From daily doses of science through daily episodes to monthly SpaceOut Google+ Hangouts with NASA JPL, DNews audiences keep coming back for more. The success of DNews has also paved the way for new original daily series, including Animalist News and TestTube Daily Show.

"DNews is a shining example of chemistry in action - exceptional talent, engaged audiences and enlightening topics all come together with the strong catalysts of Discovery Digital Networks' expertise in creating compelling web-native content and Discovery's curiosity-driven DNA," said Colin Decker, Head of Discovery Digital Networks. "By giving the audiences less of the 'what,' and digging into the 'how' and the 'why,' DNews sets itself apart on YouTube and beyond. We're thrilled with this milestone and to continue delivering insightful engaging programming through DNews, TestTube and across the Discovery Digital Networks portfolio."

DNews and Discovery Digital Networks' programming are available through YouTube, dedicated network websites, including TestTube.com, and a series of apps for smartphones, tablets and connected TVs.
