It's also possible you just think of ETH Zurich as great and automatically associate the people and products as amazing. Could be a circular dependency here.
That is indeed how things work. I can think of a few 'good' media-relevant examples, including e.g. that recent super-quick cart project [1], that reach beyond the more vanilla startup-spinoffs or basic media efforts.
I took courses online from ETH Zurich before the formula was "perfected" and I'd say they were ahead of the curve in quality, concise but info-dense educational content.
