Since 1850s, the Navy has used only capitalized letters because the teletype machines it began with had no lowercase keys. And, well, it stuck.
Now, they'll use mixed case letters when they email.
Not only will the aptly named, new NICE system look friendlier to readers, but it'll save the Navy $20 million a year. NICE stands for Navy Interface for Command Email.
The system should be in place by next year.
