By the early 20th century, bass fishing had been well established as a sport with its own following. Though the use of artificial lures for bass had begun with the artificial fly and fly fishing tackle, the bait casting rod and reel soon came to dominate the sport. Although fixed-spool reels were introduced in use in the United States as early as the 1870s, spinning reels and rods did not gain wide acceptance as an angling tool until the 1950s. Since that time, most bass anglers have used bait casting or spinning tackle, using either artificial lures or live bait (See Fishing rod, Fishing reel).
