It's become less capital-light over time - look at the games industry for example, AAA titles cost as much as a Hollywood movie. It's about a eightfold increase in real dollars per decade - and that's despite having a lot of ready-made game engine tech to build on.

Yes, there's still little in the way of overhead/operating costs or cost of goods sold - once you get a product to market, if you can acquire customers it scales perfectly up to market saturation. But the capital barrier has slowly become huge, and that suppresses innovation.

(Interesting counterpoint - when a new market opens up with low capital requirements, iPhone App Store being a case in point, it saturates rapidly and then becomes a race to zero - much potential innovation gets lost in the noise, or the market deflates so quickly that indie innovators struggle to sustain themselves financially).
