You don't expect the Beeb to use wrong words, what us the world coming to?? Should be famous residents of course.I have also heard notorious used wrongly as well.
I think there are a number of words that have now lost their original meaning and I'm afraid 'infamous' is one of them. 'Reticent' went a long time ago and so did 'hopefully'. 'Hateful' is going the same way and so is 'despise'. It's partly the effect of other Englishes and partly ignorance. When it reaches the point where you hear the solecisms all the time, you have to adapt or risk being misunderstood. Unfortunately.
