Pirelli, which is currently managing tyre concerns at this weekend's Qatar GP, had been expected by paddock insiders to win the tender for some weeks, and the deal has now been ratified by the FIA World Motor Sport Council, which was the final step in a process that had been running since March.
Having been out of F1 since 2010 Bridgestone put a propsal forward and along with incumbent Pirelli the Japanese company passed the first stage of the process, which was approval of its technical capabilities by the FIA.
