With the success of Valentine's Day, Us Weekly's Bradley Jacobs is exploring the origin of the ensemble romantic comedy, which has netted an impressive $90 million at the box office since its Feb. 12 debut.

Jacobs traces the genesis for this year's smash all the way back to the mid-90s New York Observer column that ultimately became the Sex and the City books, TV series and film franchise. A related silver screen influence? He's Just Not Into You, the successful 2009 rom-com featuring Jennifer Aniston, Bradley Cooper, Scarlett Johansson and Ben Affleck, which Jacobs says was too overstuffed with talent for its own good.
