David Charles Horowitz (June 30, 1937–February 14, 2019) was an American consumer reporter and journalist for KNBC-TV in Los Angeles, whose Emmy-winning TV program Fight Back! would warn viewers about defective products, test advertised claims to see if they were true, and confront corporations about customer complaints.
He has been on the boards of directors of the National Broadcast Editorial Conference, City of Hope, and the American Cancer Society.
He has been on the FCC advisory board and advisory board for the Los Angeles District Attorney.
Horowitz has been described as a consumer advocate; he personally shunned the description, noting that he always tried to maintain an objective point of view toward both the consumer and the businesses he profiled.
