Content: Conclusion
The invention of the telephone provided an important device for facilitating human communication. No longer did people need to be co-located beside each other to be able to converse. Through the use of the telephone, people could have equally meaningful conversations at a distance, all the while preserving reciprocity. The telephone early on was also be used as a broadcasting medium like the radio, but also allowed for the audience to respond to the commentator, which made it a two-way broadcasting medium. Today, the telephone is used as a one-way broadcasting medium for transmitting recorded messages. Telephone operators played an important role in directing telephone calls and performing troubleshooting activities as well. However, their work became increasingly redundant as the telephone became increasingly automated. Literacy was promoted through the use of the telephone due to the fact that people need to read and write in order to manufacture and operate telephone technologies. Although the telephone has been used to facilitate teaching, it is not the best medium for teaching due to the fact that discussions and interactions can be difficult to manage when classes contain a large number of students.
