The original work spoke of a burgeoning sense of excitement surrounding networked classrooms and their growing use throughout universities worldwide. Today, the picture is more complex and substantially more interesting. Driving forces, which include growing acceptance of the evolving nature of teaching and learning, high quality experiments showing what works, and a revolution in the capability, cost, and ease of use of the enabling technologies, are changing the world of education. This is evidenced by the dramatic spread of networked classrooms: today almost every K-12 school and 1 in 6 classrooms in the USA have a system. This evolution, and the interwoven forces that have produced it, make an interesting tale. But, perhaps even more interesting is the future that these events portend. This paper tries to relate the past in order to look toward that future. Beginning with a brief history of early response systems, it takes up the story from the first author's own experience leading a team through hardware barriers, misconceptions about pedagogy, and subsequent classroom successes, to summarize the variety of uses of classroom networks, and how they can lead to improved teaching and learning. It then describes the struggles to evolve the technology from 1st to 2nd generation, and a subsequent nationwide randomized control trial in the teaching of Algebra, using this newer technology, which yielded significant gains in student learning. Finally, imbedded within the narrative, are growing revelations that show why this is such a potentially important area of study for improving education, and why more powerful types of modern systems appear imminent.
