Question 1: Can you identify a relationship that has been enhanced by regular mediated interactions?
Question 2: Can you identify a relationship that was created through mediated channels (for example social networking or online dating sites)?
Question 3: Can you identify a relationship that would suffer or end if mediated channels were not available?
The short answer to these three questions is 'yes'
I want to point out that the majority of social interaction that is being "done" in this era is not face to face but rather through the internet or cellular devices. People are now closer than ever without being physically near each other when it comes to getting a message across the country, or even globe. Family members have access to communicating freely through video calls, texting, and social media with other family members in their hometowns. This is especially crucial when the time comes to leaving for college, out of state internships, and transferring from one workplace to another.
From personal experience I can say that it is easier than ever to start a relationship through social media. Whether it be amorous, friendly or strictly business relationships are made everyday through Facebook, Instagram, Snapchat, Twitter etc. For example, I have created "friendships" (more like acquaintances) with other girls solely because they comment nice things on my selfies and will act like I've known them for years when I see them in person. To an extent it reduces the awkwardness of formally meeting a person on the street and having to introduce yourself.
Now, I know of plenty of friendships that rely on social media. I for example still keep in touch with my middle school friends that if it were not for Facebook and Snapchat I would know nothing about. What they looked like, what they were doing etc. So those who no longer attend the same school, or live in the same state rely heavily on social media to be able to shoot a text, or randomly show that they still think about one another.
