Having found success in jazz, the Hammond organ became popular in rhythm and blues , including Booker T. & the .'s and other Stax Records artists.  From there, it became used in rock music , with users including Ian McLagan , Matthew Fisher , Steve Winwood ,   Mike Finnigan , Gregg Allman  and Jon Lord .  It became a significant instrument in progressive rock during the early 1970s,  and became a featured instrument in ska and reggae .  Although the original Hammond Organ Company collapsed, it was purchased by the Suzuki Musical Instrument Corporation , who continued to manufacture the instrument using several former staff for research and development.  Jazz organists, including Joey DeFrancesco and Barbara Dennerlein , have continued to feature the Hammond organ in 21st-century jazz.
