I learned that Google voice is a telecommunications service. It provides a U.S. phone number free of charge to the user. Google Voice works phones to lets you define which phone will ring bases on who is calling and lets you listen to on voicemail before answering the call. It is only available in the U.S. This information was retrieved from https://support.google.com/voice/answer/115061?hl=en
I learned that YouTube was launched in May 2005. This may one reason it is more popular then Google Voice because it has been around longer. You tube is a video-sharing website that has become an online public communication site and now operates as one of Google’s subsidiaries.
