The National Football League (NFL) and the National Basketball Association (NBA) are two of North America’s most popular professional sports leagues. They have been a part of American culture for decades, and their beginnings date back to early twentieth century.

The NFL was established in 1920 and was originally known as the American Professional Football Association (AFPA). The AFPA consisted of 11 teams from Ohio, Pennsylvania, and Illinois playing exhibition games against each other. Soon after, other teams joined the league expanding its reach to the Midwest and West Coast regions. Over time, the AFL would become simply known as the NFL with over 32 teams scattered across the United States.

The NBA started out as the Basketball Association of America (BAA) in 1946 with only 11 charter organizations. As more teams began to join, they were grouped into two conferences based on region – Eastern Conference and Western Conference – which would later become known as divisions; now as it stands there are 30 professional basketball franchises that make up the league. In 1949, after merging with another basketball organization called National Basketball League (NBL), it became known as NBA or National Basketball Association by 1949 which is still what it is called today.


The National Football League (NFL) is the premier professional American football league in the United States, with teams across the country. First founded in 1920, the NFL has grown to become one of the most popular sports leagues in the world, with millions of fans tuning in to weekly games.

This article will take a look at the history of the NFL, from its inception to today.

Formation of the NFL

The National Football League was founded on August 20, 1920, when a group of team owners gathered in Canton, Ohio, to sign the original 11-team NFL Charter. Although at the time professional football players were not given much recognition or honor, they have since become among the greatest American sports heroes and ambassadors.

Before the formation of the league, football teams had been organized at colleges and universities throughout the United States for many years. Prior to its official formation as an entity in1920, several teams had begun playing against each other under various agreements and protocols known collectively as “pro football”. The professionalization of “football” (soccer) began in England over a century ago however it wasn’t until early part of the twentieth century that there was a concerted effort by several American businessmen to launch a competitive league modeled after England’s soccer structure.

By 1920 the owners had formed a permanent structure with its headquarters in Canton Ohio and divided into two divisions; Eastern Division and Western division. The division winners would compete in an NFL Championship game at year’s end with the winner being declared champion o fthe NFL. The first championship game was played on December 4th 1921 in Chicago where University of Illinois defeated Chicago Stale; proclaimed as champions of professional football for that season. This formalized championship game format became such an integral part of football that fans from all parts look forward to “the big game” every year – now known as Super Bowl Sunday!

Early NFL Rules

Rules for the first NFL season, which kicked off in 1920 and included only 11 teams, were largely adapted from the collegiate game. The two most important rules to emerge from that season were centered on forward pass completions. First, a completed pass was worth five points rather than four for a touchdown; second, an incompletion resulted in loss of possession down. This difference encouraged passing, unlike in college football.

Subsequent modifications to NFL rules focused mainly on safety and playability. In 1933, the single-wing formation (requiring five potential receivers) was outlawed in favor of alternate formations with multiple passing options. Two years later, uniforms became mandatory and the playing field was extended 10 yards from 50 to 60 yards wide. In 1940 formations became fixed at seven players on the line of scrimmage before proceeding with play.

In 1945 rules emphasizing defensive combativeness were established and other aspects of play such as blocking (illegal until 1945), huddling (mandatory until 1941) and size limits (set at 203 lbs.) during certain times of playing a game also changed over time as did methods by which plays ended or teams ceased aerial assaults due to conditions like weather or field size restraints/constraints which have all been part of NFL rule changes over time as adopted by leagues in every area available worldwide developing dynamic sportsmanship atmosphere through rule changes each season we witness today still following these adopted practices to ensure sportsmanship remains consistent throughout play period no matter what team or location involved!

NFL Expansion

The National Football League (NFL) is the most popular and successful sports league in North America; it is responsible for overseeing the professional football teams divided into two conferences, the American Football Conference (AFC) and the National Football Conference (NFC), which each have four divisions. The original NFL consisted of just one division, with only ten teams playing in 1920. Since then, the NFL has grown to include teams from all over America and can now claim nearly a hundred years of history.

Throughout its history, the NFL has had many periods of expansion, both geographically and due to increased team ownership. As new cities were ready to support a team, or existing markets desired expansion, new franchises or existing ones were relocated. In addition to expanding across geographic borders, teams also witnessed changes in ownership from city-to-city as well as changes in conference affiliation as relocation or ownership changes took place.

Since 1920 there have been numerous relocation efforts undertaken by both owners and cities alike. One such movement was called “The Great Levels Project” that saw several teams move from their original locations — Cleveland Rams moving to Los Angeles; Pittsburgh Steelers moving to San Francisco; Dallas Texans moving to Baltimore; Miami Dolphins move back to New England; then the Patriots moved back again – all within ten years! This era of movement not only saw geographic expansion but also helped establish a true culture of AFL versus NFC rivalries that are still seen today on field when AFC and NFC opponents face each other!

In 1967 another dramatic change began when football’s two major leagues—the NFL and American Football League (AFL)— merged together forming what we now know today as the NFL. This merger created an expanded league with twenty-six franchises divided into two conferences—the National Football Conference (NFC) containing seventeen teams and the American Football Conference (AFC) containing nine—along with four divisions for each conference making up thirteen total divisions for all thirty-two current franchises. The end result? A stronger structure facilitating increased competition among teams nation-wide meaning more rivalries were born than ever before!

NBA History

The National Basketball Association (NBA) was founded on June 6, 1946 and is the premier professional basketball league in the United States. It is composed of 30 teams with each team playing 82 games in the regular season. The NBA has become one of the most popular and profitable sports leagues in the world.

In this article, we will take a look at the history of the NBA and how it has evolved over the years.

Formation of the NBA

The National Basketball Association (NBA) was formed on June 6, 1946 when the Basketball Association of America (BAA) and the rival National Basketball League (NBL) joined forces in an agreement known as the merger. At its formation, the BAA had 17 teams, mostly located in small cities and towns. By 1950, only eight of those 17 original teams were still part of the league — New York, Boston, Philadelphia, Milwaukee, Rochester and Fort Wayne from the BAA and Indianapolis and Syracuse from the NBL.

From this humble beginning in small-town arenas like Minneapolis’ Armory or Anderson’s Bombers Fieldhouse to today’s world-wide spectacle played out in multimillion-dollar stadiums throughout North America, NBA basketball has come a long way in four decades. Many modern rules were adopted during this early period along with some administrative restructuring that saw many franchises fold because of financial challenges. In 1949, for example nearly two-thirds of all NBA teams dropped out to become members of the newly formed National Professional Basketball League. In order to boost attendance numbers, promotions such as experimenting with larger venues or offering celebrity players such as Bob Cousy added a spark to what had become stale attendance figures. It worked — within five years of its inception the NBA had leaped from twelve teams to seventeen with its headquarters moving from New York City to Chicago for more centralized organization and promotion.

Season by season over several decades beginning with 1947-1948 basketball has grown into an international phenonomenon both sustianed by its fan base and established through great players such as Bob Cousy ,Bill Russell ,Larry Bird among others who have added some remarkable chapters throughout multiple generations including today’s successful stars LeBron James , Kevin Durant , Stephen Curry & Kyrie Irving who have fueled NBA’s popularity around social media platforms all over world making it one of most popular sports in North America today!

Early NBA Rules

The National Basketball Association was founded in 1946 with 11 teams. These original rules helped shape the game as we know it today. Players weren’t allowed to dunk, goaltending wasn’t a foul, and there were no 24-second clock restrictions.

Free throws: If a shooting foul occurred, free throws were awarded for each foul committed. Immediately following the free throws, play resumed from the last spot where it was stopped. This process is still used when a shooting foul occurs in the act of shooting by an offensive player only.

Field goal attempts: A player could take up to two steps after receiving the ball before attempting a field goal – if any additional steps were taken after that, it would be ruled as traveling and possession was given over to the other team.

Goaltending: No goaltending rule existed when players attempted shots close to the hoop; thus, shooters got to decide whether or not they should attempt shots against opponents that seemed ready to interfere with potential baskets! This rule has changed over time due to the amount of physical contact created while defending near closer distances.

24-second clock: There wasn’t one! Teams could move at their own pace and wait around longer before making a play. As such, points scored during games tended to be much lower than what we are now accustomed too (the early league average being in the 70s.) The 24-second rule didn’t come into action until 1954 when Syracuse Nationals head coach Danny Biasone suggested counting down from 24 seconds on each offensive possession.[1]

NBA Expansion

The National Basketball Association (NBA) has grown from a small-town organization to one of the world’s most popular sports leagues. It began in 1946 as the Basketball Association of America, founded by owners of 11 professional basketball teams from Midwestern and Eastern cities. In 1949, it merged with the National Basketball League to form the NBA, consisting of 17 teams split into two divisions.

By 1976, when both leagues had completed a merger in which new teams were established and some existing teams relocated to new cities, there were 23 NBA teams across the country. This number has since grown to 30 professional franchises throughout North America.

The first major expansion occurred in 1988 when the Charlotte Hornets and Miami Heat joined the league; this was followed by additions of another six teams over a nine-year period. The largest expansion happened between 1995 and 2004 as five new franchises joined the NBA: Toronto Raptors (1995), Vancouver Grizzlies (1995), Minnesota Timberwolves (1996), New Orleans Hornets (2002) and Charlotte Bobcats (2004).

In 2013, the NBA Board of Governors approved two additional expansion teams set to begin playing from 2020: The Charlotte Hornets will return after relocating from New Orleans (2020) and an unnamed franchise based in Seattle is set to debut for 2021/2022 season. As such, more than half of all current NBA franchises have either started or moved since 1988 contributing heavily to NBA’s growth over that period.

Comparison of NFL and NBA

The NFL and NBA are two of the most widely watched and profitable sports leagues in the world. Both began in the early 1900s and have since become major forces in the world of sports entertainment.

While their respective origins are different, they have a lot in common, such as having the same rules, regulations, and season length. This comparison article will look at the history and fundamental differences of the two leagues in order to help readers gain a better understanding of the NFL and NBA.

Differences in Rules

Though they both belong to the same league (the National Football League and the National Basketball Association), NFL and NBA rules are quite different.

In football, the field is larger and split into two sides — offense and defense — with 11 players from each team on the field at any given time. Instead of a round ball, an odd-shaped “pigskin” is used for this sport. The objective of the game is to move the ball down the field using various plays while avoiding turning it over to the opposing team by penalty, interception or fumble.

In contrast, a basketball court is much smaller and broken into four quarters (although typically only two are used in professional play). A round ball is used as opposed to a pigskin. Two teams usually occupy opposite halves of a court consisting up to five players each, who advance their ball towards one another’s baskets from their own free-throw line. The goal of basketball is for each team to score more points than their opposing team during regulation (a 4 quarter term lasting approximately 48 minutes). Overtime periods may occur if regulation ends in a tie score.

Scoring systems also differ greatly between NFL and NBA games; football teams receive one point for kicking or touching down between goalposts surrounding an endzone whereas every basket attempted on a net receives two or three points in basketball depending on whether it was taken close or further away from the “arc” — a line near centercourt that signifies certain shots being worth more points than others. Football has equipment purposes such as helmets which are required due to its physicality while equipment requirements in basketball concern safety matters such as shin guards not required by NFL rules due to its relative lack of contact overall when compared with football—players guard each other with feet instead of full body contact though certain rules like charging exist governing how much contact can take place legally per play using techniques such as sprinting, pivoting, shooting amongst others.

Differences in Expansion

The National Football League (NFL) and the National Basketball Association (NBA) are two of the four major professional sports organizations in North America. Although they share a number of similarities, the NFL and NBA have distinct differences that set them apart from one another, especially when it comes to expansion.

These differences can be seen in their respective league structures, rules, and governing bodies. The NFL is composed of two conferences — the American Football Conference (AFC) and the National Football Conference (NFC). Each conference has 16 teams divided into four divisions. Following this regional division format, teams within each division regularly compete against one another during the regular season.

The NBA is made up of 30 teams divided into two conferences — Eastern Conference & Western Conference. These conferences are then split into three divisions each consisting of five teams. Unlike the NFL’s division-based scheduling structure, NBA teams typically play each other an equal amount throughout their regular season schedule regardless of division affiliation.

In terms of expansion, both leagues have had success when introducing new teams across North America in order to attract fresh fans and generate new television revenue streams in unexplored territories. The NFL has added 12 more franchises over its history with two cities being notably awarded multiple franchises — Cincinnati & New York City each currently possess two franchise teams respectively. As for the NBA, 15 additional franchises have been added since March 1949 with venues such as LA, Chicago & Toronto all having housed multiple franchise iterations at some point across their histories.

Differences in Popularity

The National Football League (NFL) and the National Basketball Association (NBA) are two of the most popular professional sports leagues in the U.S. While both have become successful since their respective beginnings, there are some notable differences in terms of viewership, fan base, and overall popularity.

The NFL is generally considered to be more popular than the NBA. The NFL draws in a larger and more wide-reaching fan base than the NBA does. On average, NFL games are watched by millions of viewers each week while NBA game viewership tends to be much lower. In addition to television viewership, football stadiums tend to be filled to capacity whereas basketball arenas remain much less crowded on average. Furthermore, representatives of major professional sports team leagues such as Major League Baseball (MLB) have cited that more people attend NFL games than any other sporting event across all four major sports leagues combined including the MLB, National Hockey League (NHL), and Major Soccer Leagues (MSL).

In contrast to its competitor, the NBA has seen an increase in popularity over recent years due in part to its ability appeal to a younger demographic while also gaining traction from international fans coming from Europe and Asia. The 2012 – 2013 season saw a 5% growth in viewership compared to the prior season with many attributing this uptick at least partially due to global attention aimed at superstars like LeBron James and Kobe Bryant who garnered record breaking interest overseas for their individual skills and performances as well as commercial endorsements within American markets let by companies such as Nike and Adidas.


The formation of the National Football League was one of the most significant events of modern sports history. It redefined the way professional football was seen and allowed for unprecedented growth over the following years. The National Basketball Association has had a similarly powerful influence on modern athletics. From its humble beginnings in 1946, it has grown to become one of the premier sporting organizations in the world.

The two leagues have been unable to stay separate over their many decades of existence, with players playing in both and teams moving between them. They also have joined forces to create special events such as Super Bowls and All-Star Games which bring together fans from both sports.

From their respective origins, these two leagues have helped define modern sports as well as given hope and inspiration to athletes everywhere who wish to make a living off playing or coaching this beloved game we call sports.
