We tend to talk too loosely about one technology killing another, or the phenomenal growth of new media (e.g. tablets constitute, what, 2% of Internet traffic? Will that number ever be 10? 20? 50?). Anyhow these phenomena are a lot more complex than we usually recognize if we just read novelty-driven media. Past forms and technologies often hang around for way longer than anyone tells us about. There are probably far more people using explorer 5 (released in 1999) than are using tablets.

Radio will assume new roles as stuff like customized music channels assume theirs and broadband-based media reach more and more places. But I imagine broadcast–one-way, yes, but very very efficient, and, at its best, communal–will have a role. What will it be? I have some ideas ;-)
