Which Big Ten, Big 12, Pac-12, and SEC teams have been in the original conference the longest?

College athletics is once again in a season of change, with programs moving to and from conferences. Since Texas and Oklahoma announced in 2021 that they would be departing the Big 12 for the SEC, several other programs have followed suit.

At its core, the moves to other conference homes are tied to money from of TV deals, but also to recruiting future players, too.

The majority of the changes to the look of these conferences will take effect in 2024, making this academic year the last one in which certain teams play each other. Here's a look at how long teams have been in their current conference before many of them move on to the next chapter.

Pac-8 or Pac-12? The tenure of teams in this conference needs an asterisk after coaching scandals

Founded in 1915 and originally the Pacific Coast conference, the original members included the following schools:

• California

• Oregon

• Oregon State

• Washington

Other schools would join in the years after, but scandals over coaches offering financial aid and other perks at multiple programs led to the conference unravelling in the spring of 1959. Come fall of that year, five schools began playing in the newly formed Athletic Associate of Western Universities, including:

• California

• Stanford

• UCLA

• USC

• Washington

Original PCC members Oregon and Oregon State would not join the conference until 1964 and the conference renamed itself the Pac-8 in 1968. Ten years later, it became the Pac-10 with the addition of Arizona and Arizona State and rebranded again in 2011 with the addition of Colorado and Utah.

This makes California and Washington the two programs in this conference to have stuck together the longest.

10 SEC teams have played in conference since it started over 90 years ago

Playing together since its founding in 1932, the 10 original SEC teams who are still competing in the same conference are:

• Alabama

• Auburn

• Florida

• Georgia

• Kentucky

• Louisiana State

• Mississippi

• Mississippi State

• Tennessee

• Vanderbilt

Kansas is lone Big 12 team that can trace time in conference over 100 years

Back in 1907, the Missouri Valley Intercollegiate Athletic Association was born with five schools signing on. Iowa, left after one season while Washington University in St. Louis, Missouri and Nebraska leaving after 21 years.

The one school to stick around was Kansas, even when the conference became the Big Six in 1928, with Oklahoma joining just eight years earlier. The conference became known as the Big Eight after Colorado and Oklahoma State joined years later, and eventually the Big 12 when it merged with the Southwestern Conference in 1996.

The SWC, formed in 1914, included original members Texas and Baylor when the conference blended into the Big 12.

The Big Ten has 5 original members that have been in conference over 125 years

Formerly known as the Western Conference, the oldest college sports conference founded in 1896. They include the following members who are still playing in the conference today:

• Illinois

• Minnesota

• Northwestern

• Purdue

• Wisconsin

Michigan joined the conference in 1896, too, but was voted out of the conference in 1907 for failing to follow rules around games played and player eligibility. They rejoined the conference, then known as the Big Nine in 1917. It became the Big Ten in 1949 when in-state rival Michigan State joined the conference.
