Despite what some people may think, gadgets aren't just for guys, as ``Gadget Girlz'' aims to prove. The series features the latest innovations and advancements in consumer electronics and technology. The show is hosted by four women -- Carolyn Cerny, Sasha Estrada, Ethel Macasias and Janelle MacDougall -- who are collectively known as the Gadget Girlz. Each host specializes in her own area of technological expertise: engineering, information technology, telecommunications and biosciences. But the show isn't just about looking ahead at what's to come in the tech world, it also looks back through time to see how far science and technology have come.
