Proof of the level of Madonna's fame in 1991? How about a piece on the main Friday evening network news, in effect promoting her new movie!
This wasn't "Entertainment Tonight", "Showbiz Today" or "MTV Week In Rock" - this was NBC Nightly News with Tom Brokaw - Friday night, May 10th 1991!
Not only an indepth report about Madonna and her new movie, but they used "Material Girl" for the closing titles of the broadcast!
Rewind 20 years now and watch it, just as it was broadcast LIVE in the UK on Sky TV.
