Founders
(For the interesting story on how the company began, click here.)
Dr. Dilip K. Som, Ph. D. Physics. Co-Founder, President & CTO
Dr. Som has been the world’s leading closed captioning software developer since 1986. He has earned a reputation in the closed captioning community as the “guru of closed captioning” for his vast knowledge of the closed captioning field.
He has made innumerable software breakthroughs in the closed captioning field beginning in 1986 with the design, development and launching of the first PC based teleprompting/closed captioning software.
His other “firsts” in the closed captioning field include:
- Release of the first commercially available closed captioning software in 1986
- Release of one of the first time-code based professional closed captioning software in 1992
- Release of Realtime Webcast closed captioning software with total synchronization between the closed captions and audio in 2003
Dr. Som earned his Ph. D. in Physics from the City University of New York. He co-founded CPC with Sid Hoffman in 1985.
Sidney Hoffman, M.S. Computer Systems, M.A. Audiology. Co-Founder and Vice President
Sid has a over 30 years of experience in the closed captioning and teleprompting field. Sid earned a Master’s degree in Audiology (testing hearing and doing therapy with the hearing impaired), and a second Master’s in Computer Information Systems.
While in graduate school, he moonlighted as a hands-on teleprompter operator, working on shows such as the CBS Evening News with Dan Rather, and the soap operas One Life To Live and All My Children.
As a teacher of the speech and hearing handicapped he realized the vast need for closed captioning for both the profoundly deaf and those with moderate and mild hearing losses. As a practical visionary, he has been instrumental in directing, developing and marketing CPC’s closed caption products, suitably combining his academic knowledge in Audiology and Information Technology to serve the hearing impaired community.
Sid’s Master’s thesis (which was published in the Journal of the Acoustical Society of America) focused on the hearing problems of the elderly.
Sid has also received a U.S. patent for his development of a new method of teaching speech reading to the hearing impaired.
