Social networking involves individuals and organizations connected through relationships like friendships, financial exchanges, shared interests, and beliefs. It can be an effective form of entertainment and business development by connecting people with similar interests. Research shows companies that utilize social networks more innovatively score higher on measures of radical innovation. Schools are also increasingly using social networks to enhance education and connect students beyond the classroom, but need to consider how to manage student access and address issues like cyberbullying. Government agencies and other organizations have also created social networking presences to promote services, recruit employees, and collaborate with online communities. Careers in public relations often involve using social media to help businesses and organizations promote themselves and maintain positive public perceptions.
