Grid

It’s interesting how when you’re trying to conceptualise things in a diagram such as a matrix you often hit something you’d not thought of before.I’ve been constructing a grid which plots one-to-one and one-to-many against synchronous and asynchronous communication and hit this exact problem - trying to identify something that’s one-to-many and synchronous. That’s a combination more commonly associated with old media and only sometimes used in videoconferencing.But, when I looked into it there is a small but important digital development called broadcast messaging as this article explains.Contactplus is an example of the software you can use.And then, there’s cell broadcast as explained here.Thank you, matrix!
