What is the correct to write sentence first microwave were sold in 1960 Everybody use them until late

The correct way to write this sentence is:

The first microwave ovens were sold in 1960, but they weren't widely used until much later.

Here's why:

* "First microwave were sold" needs to be "The first microwave ovens were sold" to be grammatically correct.

* "Everybody use them until late" is not grammatically correct and lacks context. We need to clarify who "everybody" refers to and what "late" signifies.

The revised sentence clarifies the subject (microwave ovens), adds context about widespread adoption (not widely used until much later), and uses correct grammar.
