There are some very specific differences between a Teleseminar, A TeleWebcast and a Webinar.
I hope this explanation help you
Teleseminar: a teleseminar just uses the phone. All people
have to do is to call in, and they are connected to the call. It’s the
EASIEST technology to use, because all people need is a telephone. Long distance charges may apply.
You can have a handout with a teleseminar.
A Teleseminar You Must:
Listen by Phone ONLY
TeleWebcast: a telewebcast is where the user has the CHOICE
of calling on the phone, or listening on their computer online. All
the user has to do is to click a button and they can listen to the call
on their computer, and NOT pay long distance phone charges. There are no visuals with a telewebcast unless the speaker has a handout.
You can have a handout with a webcast.
TeleWebcast Let’s You
Listen by Phone
OR
Listen On Your Computer By Webcast
Webinar: a webinar has the user watching on their computer
as they listen on the phone AT THE SAME TIME. There is NO computer audio, just computer video and the audio portion comes through on the phone.
You typically do NOT have a handout with a webinar, as the view is
watching your screen
Webinar You Must:
Listen by Phone
