or saw each other in person — traveling by foot, car, mass transit, or airplane.
Although the travel options have remained largely the same (except that airplane travel has become much cheaper and more routine), communication options have proliferated.
On the bottom right side of Gmail is a separate section from your emails.
One icon represents your contacts, another is Google Hangouts (it's a round icon with quotation marks inside), and the last is a phone icon.
The resources are designed to support, not replace, the relationship that may occur between members of the community and existing health care professionals.
What you see here depends on what the contact has set up on their own account, whether you have their phone number saved, etc.
While phone calls remain largely between two persons (or at most, between two households on extension phones), email and IM make it easy for many people to communicate at once.
Furthermore, the cost of communication itself has gone down — whether people use the telephone or the internet.
As of July 2015, a product called Google Hangouts became the default application that allows you to chat using video and audio through Gmail.
On a desktop or laptop, you can access Google Hangouts directly from the side panel in Gmail.
