The Transformers is the original Transformers toy line that was produced from 1984 to 1991. It is sometimes titled "Transformers", the word "the" is omitted. The series was simply called The Transformers until the relaunch in 1992 was titled Transformers: Generation 2. Fans applied the name Generation 1 (later made official by Hasbro) as a method of separating the different Transformers eras.
