 Until recently, when more NFL teams have started to wear white at home at least once a season, the Browns were the only non-subtropical team north of the Mason-Dixon line to wear white at home on a regular basis.Secondary numerals (called "TV numbers") first appeared on the jersey sleeves in 1961.Over the years, there have been minor revisions to the sleeve stripes, the first occurring in 1968 (brown jerseys worn in early season) and 1969 (white and brown jerseys) when stripes began to be silk screened onto the sleeves and separated from each other to prevent color bleeding.
