1974 to now? What a stupid list! Why don't we just talk about movies released on a Thursday, with the letter "W" in them?
Face it. It means nothing.
The real stupid part is that the movie industry is the ONLY industry that counts money instead of number of units sold and/or audience size. Music, TV, books, theatre, all are concerned with how many people are buying or watching.
Movies look at dollars. Because tickets now cost $9-15 each, and cost $.35 when Gone With the Wind came out, it's ridiculous to throw out terms like "all time biggest" or "record breaker."
If you broke it down, you'd see that attendance is severely down from what it used to be, even 30 years ago, let alone 60.
So... this has nothing to do with Mamma Mia. And Mamma Mia has nothing to do with all-time, record-breaking anything.
