The RoadRunner email service is provided to the users of Time Warner Cable Internet. Access to the email is restricted to those who have Time Warner accounts and can be accessed online via browser or through the use of an email client.
The early versions of Time Warner's broadband Internet access was known as RoadRunner high speed Internet and regularly used the Warner Bros. cartoon mascot in advertising. RoadRunner email accounts often have an abbreviation of the city or region somewhere in the email address. As of 2012, the service has been rebranded as simply Time Warner Cable Internet, since Warner Bros. is no longer directly affiliated with the Time Warner company.
