Consumers have a general sense of what 2G, 3G, 4G, 5G mean in terms of cell networks. Even my school-age sons have a sense of what it means. Consumers see ads on TV and other places for the latest 5G phones, and they know that 4G and 3G phones used to be common.
Yet now Comcast is advertising 10G service, and there are no 10G phones. Of course that is because the Comcast 10G network is not a cell network - even though they offer cell service in many areas - but that sometimes escapes the consumer.
A better move would have been for Comcast to call it a "10Gig" network, but they know that very few customers on the network will actually ever see that speed. They just want to indicate it as a technical leap forward, and they want to use a very simple acronym for it. They should have sent the marketing team back to the drawing board when they coughed up "10G" though.
If you look at the comcast website you'll see all kinds of overlapping and confusing terms that they have used up to now to describe their internet connectivity options. I think I am on a "blast" plan myself, but the comparable plan has been renamed a few times since I signed up. They should really come up with a standardization for their plan names, but that might encourage people to compare Comcast claims to those of other ISPs.
