Broadcasting - from the same university Edward R. Murrow attended.
Then a Master's in Adult Education...which got me a faculty position using my broadcasting and audio/video production skills producing educational programming.
Finally, a Ph.D. in a combination of Adult Education and Educational Technology...which led to my present position in which I manage the learning technologies for a university, design classroom applications of various technologies, evaluate and mange audio video and web conferencing systems, and generally get to mess around with bright shiny toys.
I also get to solve the problems that faculty create when they either ignore or grossly misuse the technologies....not always an easy thing to do.
But the basic skills I learned in analog broadcasting and field production are still highly relevant in today's digital media. Thank you, Washington State University!
