In 1964, after three years of existence, the 29-team conference ECAC Hockey was split in two. This was done partly due to its ponderous size but also because many of the programs in the conference were competing with differing levels of investment. The conference was divided between teams that, in essence, had indoor, artificial-ice arenas and those that didn't. A special provision was made for a few programs but by and large the 14 teams that were placed in ECAC 2 either couldn't or wouldn't fund their programs to a level where they could compete with the upper-echelon programs. The split resulted in the first official delineation of divisions in college ice hockey.
