Winkler is influential in the field of digital media.
His works include Switching/Zapping[1] (1991), Film Theory, Der Filmische Raum und der Zuschauer (1992) and Computers and Media Theory, Docuverse (1997).
Another one of his works is "Search Engines: Metamedia on the Internet?
"[2] (1998), where he attempts to explain how a search engine is a black box, that is, he tries to show that the system of input and output many viewers use is not a legitimate neutral source.
He talks about how users do not actually understand how a search engine works and how it is structured, yet we make assumptions about its workings, not truly caring how or why it does what it does, as long as it delivers the information we seek.
