Media and entertainment company Discovery Communications Inc., whose holdings include the Learning Channel, the Discovery Channel, and Discovery Channel School, has acquired United Learning, an Evanston, Ill.-based producer and distributor of educational multimedia products.

Under the deal, announced Sept. 4, United Learning will operate as a wholly owned division of Discovery’s consumer products group. Terms of the deal were not disclosed.

United Learning has provided video content to supplement core curricular instruction for nearly 50 years. Its flagship product, United Streaming, is a video-on-demand subscription service offering 2,000 videos and nearly 20,000 video clips that are correlated to state standards.

While United Streaming already includes some Discovery content, company officials said the deal will give United Learning full access to Discovery’s library of several hundred thousand hours of video programming, thereby greatly expanding the range of content available through the service.

For its part, Discovery adds a proven company with 24,000 school subscribers and a different mode of content delivery: streaming video online.

“United Learning’s video library and digital delivery system, combined with Discovery’s content, will be a stronger enterprise and give us a major opportunity to grow education-related services,” said Judith McHale, president and chief operating officer of Discovery Communications.

“Our goal is to build a dynamic, multimedia business that will leverage the power of both our brands, our technologies, and our global reach to deliver world-class video products to schools around the world, ultimately … enhancing the classroom learning experience,” she concluded.
