Last month I wrote about how I think email is not used enough by brands. This month I've been thinking about other channels and platforms marketers don't leverage enough.And the big one that keeps coming back to me is why have we never seen a brand use torrents?Yes it falls into a gray area that not a lot of brands could get way with, but we need to remember of course that torrenting itself is not illegal, only the torrenting of illegal content.Although most media usage reports seem to ignore it, we know video consumption through torrents is prevalent, and in many demographics ubiquitous. So why don't we see any brands playing in this space?Even if they don't have quality branded content to release through torrents, why are no brands leveraging torrent sites through display media? Surely the lack of competition makes them fairly cheap placements and I imagine a "real" banner ad would stand out among the rest of the spam.It would be pretty ballsy for a brand to do either of these, but it would be pretty effing awesome....
