Did you ever watch the Little Mermaid? I thought it was a good movie
I sure have! that movie marked the beginning of the era known as the Disney Renaissance. Such a wonderful time for them. 
Why is it referred to as that?
Probably because that was when Disney began focusing more on animated films and some of their finest animated movies came out from that time until the early 2000's. 
Oh okay, yeah they really got better with Toy story, monsters inc and finding nemo too
Indeed, it all began back on October 16, 1923, with Walt Disney Studios
They are almost 100 years old, that is crazy to think about, matching trends for that long
Yep and I know that when the studio was making the little mermaid , they dedicated alot of time to producing short films until it eventually expanded into feature production in 1934.
