 Record executives, who had been mostly mystified by the punk movement, recognized the potential of the more accessible new wave acts and began aggressively signing and marketing any band that could claim a remote connection to punk or new wave.Many of these bands, such as the Cars and the Go-Go's can be seen as pop bands marketed as new wave; other existing acts, including the Police, the Pretenders and Elvis Costello, used the new wave movement as the springboard for relatively long and critically successful careers, while "skinny tie" bands exemplified by the Knack, or the photogenic Blondie, began as punk acts and moved into more commercial territory.Between 1979 and 1985, influenced by Kraftwerk, Yellow Magic Orchestra, David Bowie and Gary Numan, British new wave went in the direction of such New Romantics as Spandau Ballet, Ultravox, Japan, Duran Duran, A Flock of Seagulls, Culture Club, Talk Talk and the Eurythmics, sometimes using the synthesizer to replace all other instruments.
