Less than a year into its debut, DC Universe, the premium digital service from DC offering online streaming and an extensive catalog of decades of classic comic titles, has expanded its digital library to include over 21,000 single issues.

The expansion comes after several weeks of DCU quietly adding thousands of single issues to the service from the publisher's early days through titles from the early 2000s.

"We are always looking for new ways to deliver our comics and reach the widest possible audience,” DC Entertainment Chief Creative Officer and Co-Publisher Jim Lee said in a statement. "The addition of more than 80 years of iconic Super Hero storytelling to DC Universe creates a seamless experience where fans can jump from their favorite DC show right into the comic it’s based on. Our goal was to create the ultimate digital comics library and we’ve done that with this DC Universe expansion.”

In addition to its collection of television series and films, including exclusive programming such as Titans and Young Justice: Outsiders, the service offers an ever-expanding library of digital comics, with intuitive settings and download capability to read titles off-line.

"DC Universe is so much more than great video content; it's a portal to dive deep into the ever-expanding stories and art of comics The ultimate digital comic book library deepens that engagement and discovery by giving fans even more access to the multiverse of DC," DC Universe Senior Vice President and General Manager Sam Ades observed. "Given the expansiveness of the additional digital comic books we’re adding, we are excited to include more tools and recommendations to help fans jump in and explore their DC Universe.”
