If you are talking about DC power line electricity, it is no longer used in homes or industry however many electric rail systems (e.g. trolley, highspeed trains) use DC electricity as DC motors have several advantages for motive power compared to AC motors. A few very long transmission power lines use DC electricity, but the DC is converted back to AC electricity before being distributed to customers. Certain industries (e.g. electroplating, aluminum refining) use DC internally, but they use large rectifiers to convert 3-phase AC to DC electricity when it enters the plant.
If you are talking about electronic equipment (e.g. radios, computers, cell phones) these usually contain batteries. Everyone using battery powered electronics (or lighting, toys, cars, UPSs, etc.) uses DC electricity, because that is the way batteries provide electricity.
Nearly everyone uses DC electricity, in battery powered devices.
