Seven Network boss Tim Worner says the station will not be spooked into fast-tracking imported television series and dramas because of internet pirates.

Seven has just announced a range of new shows and the return of several big hits from overseas for 2013.

Revenge was a hit for Seven, despite screening six months behind the US.

Several have screened or will be shown in the US before they appear in Australia.

Among the shows Seven is screening in 2013 are the second season's of Revenge and Once Upon A Time, which have started in the US, and the third season of the period drama Downton Abbey, which is screening in Britain.
