South Korea is a huge example of this. When online banking first came to market, the only way to do it legally in South Korea was through ActiveX controls embedded in Internet Explorer because they had specific encryption requirements in the 1990s versus what IE or other browsers supported natively.

Even as recent as last year [1] it was a big deal in elections, with at least one candidate promising to end the legal requirements and allow banks to enter the modern age of browsers.
