One, Two, Three, Four...

2. The Evolution of the Internet: by the 1990s the internet had become easily accessible to the public allowing "immediate two-way communication and one-to-many communication". Paving the way for the future, the internet brought about the recognition that anything was possible. Things like blogs, youtube, and twitter came about and eventually became applications on the iPhone, made possible with wireless internet.

3. Security, Appropriateness, and Access: the internet is one of a few media that requires personal information. In recent years many ethical question have been brought up with regards to the internet. Questions like should information posted on the internet be open to the public? Or what content is or is not allowed? Many ethical lines have been crossed through use of the internet; things like spyware, an information-gathering software, allow personal data to be collected without permission.

4. The Evolution of the Radio: alongside the internet and television, the radio is the next most influential medium. It carries ideas through towns, across states, and connects countries. It was the first mass media accessible on a large scale.
