Actualitte are reporting that Darty and Carrefour have each opened an ebookstore this week. Each site will be selling ebooks encumbered with Adobe DE DRM in Epub and PDF formats. They also sell ereaders.
There are a couple rather interesting details here. First, these companies are retail chains, not tech companies. Darty's closest US analog would be Best Buy, and Carrefour are an international conglomerate of chains (similar to Kroger in the US).
They're also both using Numilog to supply and run their ebookstore. I thought I'd covered this company before but now I can't find the post. Some time back Numilog started offering an ebookstore platform that retailers could rebrand and integrate into their site. This is the first that I've heard of someone using it.
This is both good news and bad news. The good news is that France might see price competition for ebooks. And the bad news will come when some of these stores are shut down and customers lose access to their ebooks. Of course, with the tough consumer protection laws in Europe I'm not sure it will be a problem.
