In the early 1700 Boston news letter was only local newspaper in colonies?

You're close, but not quite! While the Boston News-Letter was the first continuously published newspaper in the British American colonies, it was not the only one.

Here's the breakdown:

* Boston News-Letter (1704): This was indeed the first continuously published newspaper in the colonies.

* Other Early Newspapers: Other newspapers soon followed in different colonies, such as:

* The American Weekly Mercury (1719) in Philadelphia

* The New-England Courant (1721) in Boston

Therefore, the Boston News-Letter was the *first* continuous newspaper, but not the *only* one in the early 1700s.
