Starting in 2005, the MPAA URL is added next to the Film Ratings URL. (Excluding Paramount and Sony versions) Some of the early versions have the Film Ratings URL centered, while others have it off-center to the left. The early variants were used in tandem with the MPAA URL variant until 2013.
The Universal version strictly uses the Helvetica font from the previous idents instead of the Gotham font used by Sony Pictures and 20th Century Fox, but still uses the same rating design as the MPAA's standard one.
