Broadcast message

Explanation:

A broadcast message is an identical message sent to a lot of recipients. When it is an email, it can be sent in Carbon Copy (Cc) or a Blind Carbon Copy (Bcc) form.

With the Carbon Copy, every recipients will be notified about the other recipients. In most cases all the email usernames of the recipients will be sent to all the recipients individually.

With the Blind Carbon Copy, every individual sees the message as he/she received it alone. The individual is not notified about the other recipients.

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
