Here's an example for you:
Not even ten years ago, on March 21, 2000:
'N Sync's sophomore album "No Strings Attached" sold over 2.4 million copies in it's debut sales week, with an amazing 1.1 million in just its first day.
The top-selling album in the USA last week was Pearl Jam's "Backspacer", which sold just over
184,000 copies.
Quite a difference in less than 10 years!
