There was a year-long battle on alt.dbs.echostar about the whole D* thing in 1997. I don't think there was a clear winner because D* is still in light usage compared to E*. But DSS (the combined name for DirecTV and USSB) was ruled a trademark infringement, DTV was too easily confused with digital television which was a hot topic at the time and D* (DirecTV -Star?) was just stupid and confused people due to the Dish Network name. There was never really a resolution so I always call DirecTV, DirecTV.
