I can't believe Splash was originally a foreign TV show.
Can't ITV do anything original?
Do you know anything about television?
Most entertainment formats are international, if they're doing well in one country for the right price a broadcaster would be silly not to pick it up.
In terms of creating new formats, ITV probably creates or is the first commission more formats that do well in both the UK and internationally than any other broadcaster.
Stuff that has done well internationally originally airing on ITV includes
The X Factor,
Those are the big recent big shows I can think of.
