Personally, I think you have it backwards, hard competition breeds innovation. Large companies don't have to innovate so they don't. They coast, sometimes going many decades between major innovations.

For example, Google doesn't have to change Chrome in any meaningful way to maintain (or even grow) it's market share. So, they don't. Browsers haven't changed much in a good decade and a half. That money is much better spent on marketing.
