First Choice replaces V Energy Drink, which sponsored the last series, won by cricketer Phil Tufnell. It attracted an average audience of 9.5 million with a 39% share.
The third series will air early next year; the celebrity participants have yet to be confirmed.
The deal, negotiated by Granada Enterprises and Walker Media, covers broadcast coverage on ITV1 and ITV2, online activity around the show and text voting.
