It's a persistent phenomenon: the faster we move into the future, the more we find it embedded with the bones of the past. Why else, for instance, would we still talk about “dialling” a phone, and later about “hanging it up”? Few people remember the early TV remote controls that worked by sending high-frequency sounds, but we still call remotes “clickers.” We still say “stay tuned,” “CC” (carbon copy) e-mails, “rewind” DVDs, and “post” online messages. Even new media darling YouTube contains an old-media artefact of this kind: the name is obviously meant to make us think of television, the “boob tube,” but few TVs have tubes in them anymore.
