Email domain

@comcast.com

Comcast operates Xfinity cable and broadband, NBCUniversal, Sky in Europe, and a sizeable enterprise networking arm through Comcast Business. Programmers negotiating carriage deals, ad-tech vendors selling into Effectv, recruiters in cable engineering, and supply partners chasing procurement leads regularly search for Comcast email addresses. The corporate domain is comcast.com, and the company is unusual in using an underscore between first and last name (first_last@comcast.com) rather than the more common period format.
