Why doesn't SQL Server use port 1521

Oracle uses port 1521. SQL Server uses port 1433. Why doesn't SQL Server also just use port 1521?

Specifically, I'm asking why SQL Server defaults to port 1433 and not another port.

Answer Source

You've got it the wrong way round.

1433 is the registered port for SQL Server.

The question should be, why does Oracle habitually use 1521

Mostly using standard ports makes it easier to configure firewalls.
