I can’t pinpoint the exact moment when TED talks disappeared from my feeds, but it must have been a few years now. And if we look at the TOP-10 TED talks of all time, we can see that all of them fall into the 2006-2014 timeframe. Google Trends, a great source for lazy journalists and bloggers, shows that interest in the subject peaked around 2013-2015 and has been declining ever sinceIt's called 'jumping the shark', and for me I knew it was over when David Brooks got a ted talk.
