•  AT&T and Microsoft are teaming up to enable enterprises to  connectivity across the globe. As part of the effort, AT&T is working with Microsoft to deliver an integrated IoT solution with Azure Sphere. This AT&T powered guardian device with Azure Sphere will help businesses transform their operations quickly through massive IoT deployments at scale.
• The guardian device is easy to install and provides an end-to-end solution for connecting machines and equipment to the cloud, bypassing the need for public Internet.

• If you like dividends, ATT has a dividend yield of 7.3% as of today.. However the stock has not done much over the last 20 years. But then, seamlessly connect machines and equipment to the cloud with highly secure network.. well perhaps? And who knows, perchance  they'll even manage to get HBO Max onto Roku. 

• Regarding the other half, Microsoft, they seem to know what they are doing (most of the time.)

• MSFT on  the above Log scale looks a bit more realistic.
