come a long way

come a long way idiom
Make considerable progress or improvement, as in That's good, Rob—you've certainly come a long way. This usage, which transfers the “distance” of a long way to progress, gained considerable currency in the 1960s and 1970s in an advertising slogan for Virginia Slims cigarettes addressed especially to women: “You've come a long way, baby.”
