Rockstar Games has 1 logo but changes per game/area of operation

The BLOCKBUSTER logo hasn't needed to change, with exception of the games logo for the online and in store gaming side, as people will always associate BLOCKBUSTER with rentals on new releases that they missed in the cinema or classics that they want to watch over and over again.

Logos and how they've changed

The Microsoft Xbox and the Sony PlayStation are the most recognizable console names of current times, with the logos evolving through time from the original ideas through to current logos and onward to the newest next gen consoles. Going from complex graphical images to simple memorable graphics that we all know and love. PlayStation's logo has changed a lot over the years being tweaked to try and make it more simple, however Xbox has only gone through 2 transitions after the original but is still recognizable even at a glance as the logo of a company everyone knows.

 However Nintendo has 1 logo and everyone knows it, although, it has several logos for it's separate products.
