digital marketplace creates a more direct connection between authors, their works, and the audience. Some publishing houses, including major ones such as Harlequin, have formed imprints for digital-only books in response to this trend. Publishers also offer digital-exclusive publications for use on e-book readers, such as the Kindle. One example of this was with the simultaneous launch of Amazon's Kindle 2 with the Stephen King novelette Ur. In recent years, however, the sale of e-books from traditional publishers has decreased, due in part to increasing prices. Video Recordings Videos that are born-digital vary in type and usage. Vlogs, an amalgamation of "video" and "blog," are streamed and consumed on video-sharing websites such as YouTube. Similarly, a web series is a television-like show that is shown exclusively and/or initially on the internet. This does not include the streaming of pre-existing traditional television shows. Examples include Dr. Horrible's Sing Along Blog, The Lizzie Bennett Diaries, The Guild, and The Twilight Zone (2019). Sound Recordings Digital sound recordings have played a role since the 1970s with the acceptance of pulse-code modulation (PCM) in the recording process. Since then, numerous means of storing and delivering digital audio have been developed, including web streams, compact discs and mp3 audio files. Increasingly, digital audio are only available via download, lacking any kind of tangible counterpart. One example of this trend is the 2008 recording of Hector Berlioz's Symphonie fantastique by Los Angeles Philharmonic under Gustavo Dudamel. Available through download only, it has presented problems for libraries which may want to carry this work but cannot due to licensing limitations. Another example is Radiohead's 2007 release In Rainbows, released initially as a digital download. The music industry has changed dramatically with the increase in digital music, specifically digital downloads. The digital format and consumers' growing comfort with it has led to rising sales in single tracks. This growth is clearly still underway, with all of the ten best-selling singles since 2000 having been released since 2007. This does not necessarily signal the demise of CDs, as they are still more popular than digital albums, but it does show that this changing born-digital content is having a significant influence on sales and the industry. Other Media WebExhibits are websites that act as virtual museums for any variety of content. These often use both primary and secondary historical sources, maps, timelines, infographics, and other data visualizations to showcase the
