LG is the largest manufacturer and supplier of electronics and appliances in the world. The initials LG stand for "Lucky Guys". They are the main OEM for most appliances and electronics. About five years ago they entered the US market with their name. As OEM manufacturers they make appliances and electronics to the specs of the seller.
If one looks closely at their product, specifically the plasma displays, one will notice the extras. One specifically is their ability to update both firmware and software via a flash card. You take a flash card (like one in a digital camera), insert it into your PC, access the LG site, download updates, insert the flash card into the plasma TV, and update it.
No one else offers this.
