shifting culture and other media things

In an oral culture sentences, words, and phrases can be messed up as, in the game telephone someone can say "A big dog said a word" and it can be changed to "A big dog said 'a world'" and "A big hog said 'a pearl'" and so forth. Moving to a literate culture they can write "A big dog said a word" and it would be written again as "A big dog said a word" most likely. In an oral society meanings are lost and can't be written down. in a literate society less meaning is lost. You the reader(s) and I are literate, but how literate? literacy isn't just through reading; but through ads, TV programs, pictures ect. I can translate well with certain things like ads and symbols. Facebook is on huge media site: gaming, talking, ads, TV, movies, and other entertainment substances as such; you can get onto it through your phone, IPad, IPod, computer, kindle, and more .
