These are my observations:
1. Myspace is using MYSPACE.TV to direct visitors to the Myspace Television website.
2. They are using a method that does not re-route visitors to another domain even after lengthy navigation of the website.
3. The site administrators have placed a graphic in the upper right-hand portion of the home page that contains the text "MYSPACETV" with the "TV" portion in smaller letters. At first glance, this could be mistaken for a TLD extension.
This "may" be indicative of a strategy to slowly transition to the full adoption of MYSPACE.TV for their Television website.
Hope this helps.........
