Which toy product do children like most this year?

Ml: Our market investigation showed that there is a growing demand for the toy products.
M2: Yes, our toy "Superman" is very popular with children. Our sales have been increasing steadily.
M1: I know, but I think kids and teenagers like "Cyber Cop" better, which is made by Kito, our major competitor. It sells even better than "Astronaut", the children’s favorite last year.

M: Well, what about our sales from 1998 to 2000.
F: Oh, terrific. There’s been constant growth from 1998 to 2000.
