LOS ANGELES (Hollywood Reporter) – History is looking to make "Pawn Stars" into its "CSI."

After already conquering Las Vegas, the cable network wants to spin off its top-rated reality hit -- not just once but twice -- launching editions in New York and Miami.

"Pawn Stars," which launched last year, chronicles a family-run Vegas pawn shop that deals in a variety of antique and historical artifacts. It pulled in 5.1 million viewers on Monday, a series record for the network.

The expansion plans, still preliminary, would boost the number of reality shows on the network after a record-setting February driven also by unscripted titles "American Pickers" and "Ax Men."
