Seems that Yahoo Go TV is no longer being promoted through the Yahoo.com website. It used to be located here:
…and now these page redirects to Yahoo Go, Yahoo’s rich client for mobile devices.
UPDATE: This post in the Yahoo forums says it’s a temporary mistake. Possible I guess.
UPDATE 2: As Pablo from Yahoo points out in the comments, Yahoo Go TV is back up and running.
Hey Rakesh, Pablo here with Yahoo! Connected Life group. The site was temporarily down for maintenance and is now back up and running. You can still download Yahoo! Go for TV at http://go.connect.yahoo.com/go/tv.
