I want to know the answer to the following question:
In what year was the iTunes Wi-Fi Music Store introduced?
All the background I'm provided with is that "This service allows users to access the Music Store from either an iPhone or an iPod Touch and download songs directly to the device that can be synced to the user's iTunes Library over a WiFi connection, or, in the case of an iPhone, the telephone network.". Is that enough to answer the question?
Answer: no
