Who Invented The Dot? Poem by Paul Reed

Who invented the dot?
That is, the dot in 'dot com'
For now there are dots everywhere
Where did they all come from?

The fella who invented the dot
Must now be a billionaire
Wallowing in a sea of his own dots
With cash floating in the air

I wish I'd invented the dot
And sold them at a penny a time
I'd now be a few quid richer
Without resorting to crime

The next big invention
Could be a new type of comma
Maybe a comma but with wings
A bit like a Lancaster bomber

That leads me to another question
The difference between a dot and a full stop
This is a particular query
That I'm not prepared to drop

If there is anyone out there
Who could answer this question with ease
Please get in touch as soon as possible
Answers on a postcard please
