Netflix is partnering with Microsoft for its upcoming ad-supported streaming tier, the company announced Wednesday.

The streaming service says Microsoft will become its “global advertising technology and sales partner” upon rolling out the cheaper option.

“It’s very early days and we have much to work through,” Netflix COO Greg Peters writes in the post. “But our long term goal is clear. More choice for consumers and a premium, better-than-linear TV brand experience for advertisers. We’re excited to work with Microsoft as we bring this new service to life.”
