Having a record-breaking year at the box office is both a blessing and a curse — a curse because it sets a new benchmark that Hollywood has to live up to.

The 2007 domestic B.O. clocked in at $9.62 billion, giving the film biz its best year on record, according to final tallies released Wednesday.

That reps a 4% bump over 2002, the previous record-holder, and a 5% gain over 2006, according to Rentrak and Nielsen EDI.

Admissions, however, were up only 1% over 2006 and down from 2002.

In another first, all six majors jumped the $1 billion mark at the domestic box office, with 20th Century Fox crossing over during the last weekend of the year on the strength of runaway hit “Alvin and the Chipmunks” and “Aliens vs. Predator — Requiem.”

In terms of market share, Paramount won the crown thanks to DreamWorks, posting total receipts of $1.49 billion, up 55% from last year.

Warner Bros. posted box office of $1.42 million, gaining 34%. Disney came in third, posting receipts of $1.36 billion, down 9%.

Sony was down 27% from last year, with total box office of $1.24 million in 2007.

Universal posted receipts of $1.1 billion, a 38% gain.

Fox saw box office of $1.01 billion, down 28%.

New Line made $485 million at the domestic box office in 2007, gaining 93% over the previous year. Lionsgate was up 11%, posting total receipts of $368 million. MGM made $363 million, up 122%.

Market share does not measure profitability. Also, the studios turning out more titles will consequentially have bigger grosses.
