Martha Stewart is a television personality and cook that has spent many years teaching others how to cook. Throughthrough both television and cook books she has written. Martha Stewart has a very warm and knowledgeable presentation. Her tone is kind, softhearted and reinforced with a warm smile to help you feel like she cares about the audience. She gives backstory about her recipes and specific instructions for each step of the process that she is executing right in front of her viewers. I find Martha very believable because she seamsseems knowledgeable on the subject of cooking and I grew up with my mother cooking food from her cook books. The level of professionalism and teaching by example helps to instill ethos to viewers. Even though they might not have previously known who Martha Stewart is or her background. Just, just by listening to her talk and observing her actually making the recipe instills the confidence of the viewer that she actually knows a lot about the subject.
