### Instruction: Provide bulleted list of the years mentioned and what happened in that year in the format {Year}--{What happened}
### Input: There have been minor changes to the uniform design throughout the years, such as changing the silver stripe patterns on the jersey sleeves, and changing the colors of the jersey numbers. "TV numbers", which are auxiliary uniform numbers to help TV broadcasters identify players from the line of scrimmage, were added to the jersey sleeves in 1956. White trim was added to the logo in 1970, with outlines (white on the blue jersey, silver on the white jersey) added to the numbers in 1972; the color arrangement on the numbers on the blue jerseys was reversed in 1982. The silver facemasks became blue in 1984. In 1998, the team wore blue pants with their white jerseys along with grey socks but dropped that combination after the season. In 1999, the "TV numbers" on the sleeves were moved to the shoulders.
