Love Appears on and off Set of the Big Bang Theory: Find out Who’s Dating Who.

The Big Bang theory first aired on September 24, 2007. And boy, did it make a bang. The sitcom was a hit from the very beginning, with geeks and cool kids falling in love with the quirky group of science nerds. The sitcom lasted for 12 years and is still going strong. This TV show was revolutionary in that it finally showed the socially-awkward nerds getting the “eligible” girls and not being rejected.

Developing Relationships On and Off Screen

As it goes on many long-running shows where cast members are together for most of the day every day, relationships form, both on and off screen. The most talked about relationship was between Leonard, the experimental physicist, and Penny, the aspiring actress who lives next door. Penny would usually only date tall and muscular men, but she ends up falling in love with Leonard and the two date on and off until they got married.
