Can the Auracast™ word mark be used in a web domain, such as www.auracast.com, or www.auracastbroadcast.com?

No. As the Auracast™ word mark is a trademark owned by thte Bluetooth SIG, it cannot be used in a domain name. If you need to use the Auracast™ word mark in a URL, it must be placed after the back slash - e.g., companyname.com/auracast.

An example of correct usage for the Bluetooth word mark in a URL is www.motorola.com/bluetooth.
