I made a few rough sketches on different concepts. After deciding on the old TV, I fired up Photoshop and created a 1024×1024 px document with guidelines creating a workspace reaching 512×512 px.
I collected some reference photos on old TVs and started to block out a rough composition. I wanted the TV to be innocent and cute, young but still old almost like WALL-E. I realized the antennas was perfect for signaling a certain mood and to make it more cute, and I went for a simple and symmetric look for the finalized icon.
