4 Seven has show Simpsons before. It was only as recently as last year they used to air a marathon of them on there on Saturday nights which they have now stopped doing.
They started showing them on Saturday afternoons for a while, as late as a few weeks ago but they’ve stopped again.
I’d like to think it’s probably as part of a new deal which includes it as a catch up option. Programmes like Frasier and Everybody Loves Raymond have appeared on 4Seven in the last few months also.
