One of the recent addition to SharePoint Online space is Communication sites! The modern SharePoint Online communication site templates are designed to broadcast information to a broader audience such as to an entire organization or teams to keep them informed and engaged.

Create a New Communication Site in SharePoint Online
To create a communication site in SharePoint Online, follow these steps:

• Login to New SharePoint Admin Center as a tenant admin or SharePoint Online Administrator. 
• Click on "Sites" >> "Active Sites" from left navigation >> Click on "Create" >> From the  options available, choose "Communication Site " to create a new communication site collection.
  
• Give the site a name, which becomes the URL of the site. You can edit URL as well below it if needed. These sites are created under the /sites managed path by default.
• Choose a template for your site - it is just a starting layout, you can change it later anyway. I've selected "Topic" here!
  
  
• Optionally, under the "Advanced settings", select the language and set the description by adding some text that lets people know the purpose of your site and then click Finish.

SharePoint creates the communication site quickly and will appear on the sites list. Now, we can populate it with our own information. When ready, You can share it with other people by adding the permissions and sharing it with others. Communication sites don't come with an Office 365 group. 

You can also use the "SharePoint Home" (https://tenant.sharepoint.com/_layouts/15/sharepoint.aspx) to create communication sites by simply going to: Office 365 App Launcher, click on SharePoint.
Here is where communication site templates fits well:

• A typical Intranet-Extranet-department sites.
• News Portals, Product or Service oriented sites,
• Campaigns, insights, Events, usiness highlights and reviews
