In a rare public feud between large technology companies, Amazon.com Inc said on Tuesday its Echo Show devices could no longer play videos from YouTube because the site's parent, Google, stopped supporting the service.

The spat is the latest in Silicon Valley in which competitive tensions stood in the way of customers. Amazon and Google square off in many areas, from cloud computing and online search, to selling voice-controlled gadgets like the Echo Show.
