I was lead to believe you could see The Big Bang Theory full episodes from season one. And after I paid and upgraded to full episodes, customer service was slow in response and would not answer my question directly, but continued the semantic-game-playing by saying all full episodes are available on the desktop view. So in truth, CBS only has full episodes of Big Bang Theory from season ten. The show 60 Minutes should do a report on their parent company.
