We’ve written about Webdoc several times this year, most recently when it won the Music TechPitch 4.5 event at EMI’s headquarters. The startup has officially launched its service this week, though, and is already building a big buzz within the industry. As explained before, Webdoc helps people create online widgets mixing photos, music, video, text and links, pulling in content from Facebook, Twitter, Instagram, SoundCloud and other apps. The Guardian is using it on the newspaper’s music Tumblr, it’s the basis for EMI’s Pink Floyd treasure hunt (Bulletin, 30-Nov-11), and it’s also been used for Nirvana, Jamiroquai, PIAS and NME.com. “You use Webdoc when a status update isn’t enough to tell your story, but maintaining a blog is too much hassle. We think it’s pretty magical, and will make communicating online even more fun and expressive,” says CEO Stelio Tzonis.
