The station broadcasts indie, hip-hop, alternative, punk, electronica, rap, dance, classic rock, jazz, and country music.

In 1948, the college had obtained a construction permit for a station at 89.9 MHz;[10] at the time Albertus Magnus Hall—the science building which housed the studios—was built, it was mentioned that the plans included FM broadcasting.

[11] After going on the air on March 15, 1966,[12] WDOM increased its broadcast hours—airing ten hours a day[13]—and expanded its sports coverage, including freshman basketball and varsity hockey games.

[16] It had expanded its broadcast day to 21 hours by 1974 and was airing a mix of progressive rock, in-house educational and block programming; it also began to seek a power increase.

[16] The station's classical record library received a major boost when the former WPJB-FM, which had exited the format, donated its collection to WDOM in 1976.

[1] In the immediate aftermath of Hurricane Sandy in 2012, WDOM broadcast Rhode Island Public Radio when WELH, then the network's main transmitter, was knocked off the air.
