has television  destroyed communication among friends and family?

i agree with that, television has destroyed communication among us.
for example, when i go to a bar with friends and there is a tv which transmits (better: is showing) a football match , everybody is watching that instead of talking with each other, even if i try to start a conversation, this does not continue for a long, So, when a tv is in the same place where a meeting is, it can interfere with communication.
another example, is when i'm tired of working and i just want to relax, i turn on the tv, expecting to avoid all kinds of communications with everybody, and that actually works. nobodies bothers me, when i'm watching my favorite program. that why watching tv inhibits people from starting conversations.
finally, i have experienced, when i try to tell something to a friend and he is watching tv, he doesn't even care about what i'm saying. He tries to show me that he is listening to me, but at the end when i try to ask for some advice about my situation, i found that he spent the whole time watching tv instead of listening to me. so, watching tv while a friend is talking to you causes bad communication.
For those reasons, i agree that tv has destroyed communication with friends and family.
