Product placements in music videos are nothing new.  But while not quite reaching Lady Gaga proportions (does Britney beat Gaga by any metric these days?), her new video for "Hold It Against Me" certainly tries.  There are a lot of references to products from Sony, who own her record label, and to online dating site Plenty Of Fish. But there's more. How many product placements can you find in the new Britney Spears video?
