A server-based Internet service, with client-side applications, is described that enables users to communicate between electronic devices such as smartphones, tablets and personal computers by broadcasting live video, voice and / or text via an internet protocol (IP) address. Broadcasting can be done in both private and public formats. Private broadcasts can be made ‘one-on-one’ between two registered users or among a group of private contacts. Public broadcasts can be accessed by any registered users and can also be transmitted to registered ‘Followers’. In addition to designating ‘Followers,’ users can also designate types of content that they wish to follow, e.g. video, voice and / or text. Broadcasts are stored on service provider servers where they can be searched by title, category, proximity or by description, and accessed at a later time. Broadcasts may also be designated as ‘Favorites’ for easier access in the future. Once accessed, broadcasts can be organized alphabetically or chronologically.
