What is meant by Postmodern Media?

Postmodern media is a term to categorize the wide selection of media products spanning mostly after the first and second world war.
  The main element that links postmodern media texts together is how they offer a more stylistic story, focusing less on the depth and complexity of the actually narrative in favour of trying to convey a big picture through use all elements of media (visual, audio, narrative, advertising etc).
  It is a recycling of past ideas and merging them together (convergence) to create something which appears original yet familiar.

The effect that this has had on the progression of media is rather interesting. Instead of new brands we get rehashes in all forms of media. The video game industry releases a new version of COD (a military simulator with a thin story mostly focusing around the online multiplayer aspect) and FIFA (a football simulator again mostly focusing around online multiplayer) each year.
  This is essentially the same game with a few tweaks, however since that the whole purpose of is directed at playing with friends, most people are forced into having to buy the new game, because either no one will be playing the old one online or the game producers simply shut down the servers forcing people to buy the new game.
  This means that the games company can generate millions of pounds of easy renewable revenue each year by simply dictating what the purpose of the game is about.

The movie industry is in many ways becoming like this, each year releasing a re conceptualizing of an original idea, or re releasing an old movie in 3D (adding only a thin layer of noticeable content whilst gaining a massive profit). This lack of meaning almost appears to be pushed by the film makers more and more as time moves on, such as is the case within the film Avatar. Taken by the face value of the movie, it would appear to be a whole conglomeration of different ideals and philosophies trying to converge into one, which is shown metaphorically in the movie by the way that theres this giant seintiant tree connecting all life on the planet, how the lead character is only living a life through a Avatar (this being a reference to not only video game avatars but also the spiritual concept of the soul in the human body). There is a giant distructive force shown by the humans ( the ironic message being that we are the monsters, instead of the aliens).
   However whilst it does get all of these messages across very well, it lacks a certain feeling of purpose, almost gives the impression that they put a load of ideas into a hat and then pored out on a table, rearranged and then created a separate picture for each one, without properly (and most likely purposefully) giving them a point for being. Such as is the irony of Doug las Adams "answer to life the universe and everything" being "42". Both stories give a sense of scale and grandness whilst leaving the audience slightly baffled by their ultimate lack of meaning. This is the definition of post modern media.
