Hello how may I help you? Hi! Can you tell me what the best selling record of all time is? Yes, I can help with records. Are you referring to best selling record of all-time in the US or world wide? I would like the US record. The Eagles greatest hits sold 29 million copies. Wow! Thank you for that information. You are welcome. What else would you like to know? Can you tell me the world wide record as well? Michael Jackson's Thriller sold 66 million copies worldwide. Wow! That's amazing. That was my last question. Okay. Have a great day.
