| Quite a few of these no longer stand for anything. ESPN (since 1985) and AMC (since 2003), I'm sure of. GSN, MTV (in the US), and A&E might also stand for nothing now, but I can't find any specific evidence with a quick search (other than the fact that they never use the full name in any context anymore).
They do this when they expand beyond their initial focus and don't wish to lose their established brand, but want to avoid being contradictory. |
