After access to YouTube was pulled from one of the device of the online retailer, the search giant Google and the online retailing giant Amazon fought publicly. YouTube stopped working on the Echo Show of the online retailing site on Tuesday.

Echo Show delivered a broken user experience: Google

Echo Show is a voice-controlled assistant with a screen that can display both videos and information. Google and Amazon issued statements criticizing one another after access to YouTube was stopped by the former company. The U.S.-based e-commerce giant said that the search giant had blocked YouTube on the Echo Show “without explanation.”

The Echo Show delivered a “broken user experience,” said the ads giant. The Echo Show could play videos from YouTube but it did not provide all of the functions of YouTube like the ability to serve up video recommendations or subscribe to channels.

In a statement, the ads giant said, “Amazon’s implementation of YouTube on the Echo Show violates our terms of service, creating a broken user experience. We hope to be able to reach an agreement and resolve these issues soon. We’ve been in negotiations with Amazon for a long time, working towards an agreement that provides great experiences for customers on both platforms.”

Amazon, however, said in its statement that the ads company has chosen to no longer make YouTube available on Echo Show, without explanation and without notification to customers. The tech company said, “There is no technical reason for that decision, which is disappointing and hurts both of our customers.”

Both companies competing for the same growth opportunities: Analyst

This is not the first time that the tech companies have removed their rival companies’ products from their platform. The search giant ordered the Windows maker in 2013 to remove its unofficial home-made YouTube app from the Windows Phone store event when it provided an official app.

The ads giant said that the app of Microsoft violated its terms of service by allowing people to hide advertisements and download videos. Jeff Bezos, the CEO of Amazon said in 2016 that the retail giant had stopped selling the Apple TV video-streaming box because both Google and Amazon had not agreed acceptable business terms to include Prime Video service of the latter company on the device.

Currently, both the company are developing rival voice-controlled smart home speakers that can act as a gateway to profitable services. Ian Fogg, an analyst at the IHS Markit consultancy, said “Both companies are coming into conflict because they are competing for the same new growth opportunities – in this case, around the smart home.”
