[摘 要]在新闻受政治因素约束的中国大环境下，外界普遍认为中国新闻是专制的，没有民主。加上我国将新闻定义为党和政府的喉舌，更加加深了这个映像。其实不然，早在20世纪出中国新闻平民化就已经产生，由于当时大环境的约束到20世纪末才能够发展。

　　在媒介平民化曲折前进的过程中，白话文的出现、报纸广告的出现、报业集团的产生、都市报的兴起、民生新闻的兴起都加快了媒介平民化发展的脚步。

　　随着科技的发展，网络技术将世界联通在一起，微博就是这样一个“泊来品”。麦克卢汉曾说过：“媒介的产生和运用宣告了我们进入一个新时代。”微博不同于传统媒体中的线性传播模式，也不同于网络媒体中的网状传播模式，而呈现出一种新型的“分裂式”传播。但是微博作为一个新生事物，在中国的发展只有短短几年时间，发展还不成熟。本文主要探讨微博在媒介平民化进程中扮演的角色。
