Which of the following sentences is correct?

The History of the Bubble Gum.

The History of Bubble Gum.

Thanks guys...
Hi Alda

Neither of those is a sentence.

As a title, I'd use The History of Bubble Gum.
The History of Bubble Gum.

If you use the definite article "the" you're talking about a specific bubble gum. Well what other type of gum would there be?

The History of the Car. - That's okay - because you could also have the history of the truck.
The History of Car. - Wrong
The History of Cars. - This is also okay.

If you were using a proper noun, omit the.

The History of Ford.
The History of Canada.
The History of Kleenex.

The History of Hair Gel. (Right)
The History of the Hair Gel. (Wrong.)

 Yankee's reply was promoted to an answer.
We use THE + singular noun to make general statements about animals and about inventions and discoveries. For instance:

Who invented THE bubble gum?
The fly is a common insect.
The electron is a part of every atom.

But, a plural noun or an uncountable noun on its own has a general meaning without using THE (eg. Cars are expensive in my country / Bubble gum is harmful for your teeth.)

What d'yu think would be the answer to your question?

Thanks Yankee!
Yeah! They're not sentences.
