2. On Jay-Z's involvement with the Nets:
He helped design the team logos and choose the team’s stark black-and-white color scheme, and personally appealed to National Basketball Association officials to drop their objections to it (the N.B.A., according to a person with knowledge of the discussion, thought that African-American athletes did not look good on TV in black, an assertion that a league spokesman adamantly denied).3. History:
the Danish King Harald Blatand ate so many blueberries that his teeth stained blue. "Bluetooth" is named after him because of his ability to unite warring Scandinavian factions, just as Bluetooth unites wireless devices. The Bluetooth logo is also a combination of the King's Runic initials.
