Is Power BI free? How is Power BI licenced?

The Power BI Desktop is a free download and you can register for the Power BI Service at no cost (with a business email address). This enables anyone to easily start building reports. The Power BI Service becomes a paid requirement when you wish to share and distribute reports to other users within your organisation. Each user will require a Power BI Pro licence and this is activated within the administration of Office 365.
