Duracell unveiled the latest broadcast commercials this month in its highly successful "Trusted Everywhere" advertising campaign. The 30-second and 15-second television spots depict the life-saving work of Air Life Denver, an emergency rescue transport service that uses a variety of vehicles including helicopters as well as high-tech personal devices to rescue families affected by severe weather. This year's campaign will also feature a 60-second radio spot that highlights the efforts of the WX4NHC, an amateur radio station located at the National Hurricane Center. WX4NHC is operated by a group of volunteer amateur radio operators who communicate critical severe weather information to first responders in remote storm locations across South Florida.
