In 2000 Callaway introduced the Rule 35 golf
ball. Established as a premier clubmaker, Eli Callaway successfully enters the
golf ball market. Advanced technology in core and cover design quickly elevates
Callaway golf balls in the marketplace. By 2009 Callaway golf balls such as
CB1, HX Tour I, Big Bertha and the Warbird push the company’s golf ball
division to the 2nd best selling golf ball company. Today, models
such as Chrome and Chrome Soft maintain the popularity of Callaway golf balls.
