4K (computer virus)
4k is a computer virus which infects COM files and EXE files. The virus was one of the first to employ stealth tactics. Infected systems will hang, after September 22 every year, which is also the date of birth Bilbo Baggins, a character from "The Lord of the Rings". The code was intended to display the message "Frodo Lives", but hangs in all known variants.
DirecTV
In November 2014, DirecTV became the first television provider to begin offering 4K ultra-high definition content. On launch, 4K content was limited to renting a small library of on-demand films, downloaded to the subscriber's Genie DVR (some 4K content can also be pre-loaded automatically to the set-top box via the Genie Recommends feature). The 4K service could also only be used on "DirecTV 4K Ready" televisions, which support RVU protocol; this was limited to selected Samsung 4K televisions released in 2014.
