Browser enabled communication device for conducting conversations in either a real-time mode, a time-shifted mode, and with the ability to seamlessly shift the conversation between the two modes

A communication device, comprising:

• a processor;
• a display;
• a network connection configured to connect the communication device with a remote communication device over a communication network;
• a browser;
• and
• a communication application configured to enable communication with the remote communication device over the communication network,
• the communication application and the browser both running on the processor and cooperating to create a user interface which enables a user of the communication device to participate in a conversation with the remote communication device over the communication network, the user interface enabling the user to participate in the conversation in either:
• (i) a real-time mode;
• or
• (ii) a time-shifted mode;
• and
• (iii) to seamlessly transition the conversation between the two modes (i) and (ii) so that the media of the conversation may be rendered synchronously when in the real-time mode or asynchronously when in the time-shifted mode.
