The theory of some, including myself, is that RT stands for some Indian bigwig named Rizvi Traverse. See link for further, read the past posts, or google him. He makes more sense than Tillerson or Real time equaling RT.

Info on Rizvi Traverse

Also, "Rizvi maintains an elusive Web presence. The only readily found picture of Rizvi is a snapshot of him sitting with Twitter CEO Dick Costolo and Alwaleed in a New York hotel after the prince bought Twitter shares."

I was trying to get caught up when the idea of it being the new CEO of Cambridge Analytica occurred to me. I have since seen the India investor in twitter connection as RT and that does make a lot of sense.
