I want to know the answer to the following question:
What were the designations of the two redesigned 360 models and when did they come out?
All the background I'm provided with is that "Although not the best-selling console of its generation, the Xbox 360 was deemed by TechRadar to be the most influential through its emphasis on digital media distribution and multiplayer gaming on Xbox Live.". Is that enough to answer the question?
Answer: no
