As far as i can tell, yes. The only change in football that i can find is the value of a field goal.

G'day Cowtipper, Thank you for your question. Yes, it has. American football evolved from rugby which also has fields of 100 yards.

The football field was 110 yards long with no end zones until 1911. There were other changes in football through the years. Once field goals were worth more than a TD, for a few years TDS were worth 0, only giving one a chance at a kick for "goal". The current scoring system settled at the current points alloted in 1905. Once it was 3 downs to make 5 yeards, then 3 downs to make 10. Once forward passes were illegal, then at first an incomplete pass turned to ball over, later was a penalty. Until 1920, the extra point was from wherever the ball crossed the goal line, had to be from place kick a few yards from taht spot it crossed the goal line, or one had a free kick called a punt-out to reposition the ball for the kick. Canada still retains a smattering of the old rules, the 110 yard field for instance, the one point "rouge" as well plus other rules like 12 men aside and a 25 yard end zone, that evolved in Canada. Here are the scoring changes: FG TD PAT Safety 1883 5 2 4 1 1884-1896 5 4 2 2 1897-1903 5 5 1 2 1904-1908 4 5 1 2 1909-1911 3 5 1 2 1912-1957 3 6 1 2 1958-1987 3 6 1or2 2 1988- now 3 6 1or2 2 + 2 points for defensive return of failed PAT. 1 point for a safety if one occurs on PAT attempt. In 1922 PAT 1st allowed to be scored on run, pass or drop kick from 5 yard line, for 1 point. Before this the PAT was only allowed by placement. *In Philadelphia Interscholastic football, a kick-off that went through the goal posts was (still is?) a field goal worth 3 points! *N.F.L. Europe awards 4 points for FGs of 50 yards or more. *Arena Football awards 4 points for drop-kicked field goal and 2 points for drop-kicked PAT. *The N.W.F.A. awards 2 points for PAT by kick, only 1 point for PAT by run or pass. *The Maritime WFL awards 2 points for a convert by place kick, as did the NBWFL. •In 6-man football, a FG is 4 points and a kicked PAT is worth 2 points. °In the W.F.L., a TD was worth 7 points, the point after was worth 1 point, & had to be by run or pass.

American Football? No. In the beginnings 1869 - 1880s, field size varied considerably. They've been 100 yards from goalline to goalline since about 1911.

Current 8 man football is 80 yards.
