Let’s start off by getting some terms straight. Properly speaking a teleseminar is learning content (specifically a seminar) which is executed using a telephone conference call (a teleconference). However, many people use the term as as a synonym for teleconference. A marketing teleseminar is really a teleconference in most cases. A telephone call between two people is also a teleconference, specifically a point-to-point one. Most of the time the word teleconference is used to refer to a multi-point call involving several telephones.
