TED talks represent a passing middle-brow phase
Despite the outcry over teens and texting, the Internet has been one of the largest booms in literacy, depending on how you define it. If you define literacy as not just the ability to read words, but the spread of words, and all that comes with it, ideas, culture, etc., then the Internet has been rocket fuel. This is why the bar for quality television shows have risen so much, people are overwhelmed with so much content that they can be selective.
But this also raises the bar for what is and isn’t middle-brow. The fascination with TED talks may, in retrospect, be viewed as a relic of “early” Internet, whereby the bite-sized packaging of stimulating thought-pieces filled a vacuum of the newly expanded appetite for good content. People may then quickly graduate from watching those talks to reading long-form non-fiction, where ideas can be more substantially examined. Despite all the cries of the downturn of publishing, The New Yorker readership is up, The New York Times is doing well, book sales are up, etc.
It’s like when the paperless office was supposed to be the death knell for paper. Instead, people need paper so much more than ever. Information consumption as a whole is up, but it’s just been aggregated so well, that the old way, where content hit people in the long tail of local papers or local programming, has dried up, and now the real, meaningful pillars of content will shine through.
