How to make a lowercase trademark / TM sign in HTML5?

Question

I know that ™ creates an upper case TM sign like so: ™.

I was wondering if it was possible to do the same thing with a lowercase "tm"?

Answer 1

Use <sup>:

<sup>tm</sup>

For example:

Testing<sup>tm</sup>

Generates (since it is one of the allowed HTML tags in SO's markdown):

Testing^tm
