Hey CH, We are KMSINFOTECH, We are submitting our sixth design. This is a very basic design with perfect color combination and the one which fulfills all your requirements as requested in project description. We have used a microphone to represent the talk show using chat bubble, and a radio to broadcast that talk show. We have also created a mock up for this logo design. If you want some more modifications, please let us know. Do rate our designs to let us know, if are moving on a right track. The final design will be submitted in all possible formats.
