According to IMDB, BB was the tenth top selling DVD of 2005, with 6,15 million copies. Among the movies released at theaters in 2005, it lost only to SW and Madagascar. Among PG-13 movies (animation and PG movies dominate the DVD market), including the older releases, it lost only to SW. It outsold movies that beat it theatrically, including WOTW, CATCF (a family PG-rated movie, no less) and Mr and Mrs Smith (beat it worldwide on the BO). FF sold 2,4 m in the first day, but probably dropped high after that, in three weeks it wasn´t even in the top eight selling DVDs anymore and it didn´t make it to the top ten. it´s not uncommon, some DVDs make 70% or more of its sales in the first day.
