The Big Bang Theory S01: A Complete Guide to the Season That Started It All

Before the world knew about "Bazinga!" as a catchphrase, before Sheldon Cooper became a pop culture icon, and before the show held the throne as America’s #1 comedy, there was simply a pilot episode and a dream. The keyword Big Bang Theory S01 represents more than just a collection of seven episodes (yes, the first season was famously short due to the 2007-2008 writers’ strike). It represents the humble, awkward, and brilliant birth of television history.

2. Leonard Hofstadter (Johnny Galecki): An experimental physicist and Sheldon's roommate. Leonard is the show's everyman, often caught between his love for science and his desire for social acceptance.
3. Penny (Kaley Cuoco): A waitress and aspiring actress who lives across the hall from Sheldon and Leonard. Penny's character serves as a bridge between the scientists' world and the "normal" world.
4. Howard Wolowitz (Simon Helberg): An aerospace engineer and Sheldon, Leonard, and Raj's friend. Howard's short stature and mother-issues are recurring joke themes throughout the season.
