In 1953 he established Meadville Master Antenna (MMA), a cable TV system, with help from Milton Shapp of Jerrold Electronics.

[3] To avoid any appearance of conflict of interest, since he was legal counsel to various cable operators, Barco refrained from expanding MMA.

He proposed different channels aimed at young children, high school youth and adults, with the programming supplied by the Pennsylvania Department of Education.

[11] There were delays and difficulties, but in the late 1970s the Barcos teamed with Joey Gans in setting up the non-profit Pennsylvania Educational Communications System (PECS).

[12] Barco's son-in-law, James J. Duratz, husband of Helene, worked with Joseph S. Gans III to build the network.

"[14] From the early 1950s George and Yolanda Barco, who had also become a lawyer and worked closely with her father, represented the cable TV industry in several important lawsuits.

[15] The Barcos launched a test case for the NCTA in Meadville, where they and one of their subscribers, Gus Pahoulis, sued for recovery of $70.40 paid in 1953 and 1954 for the 8% excise tax on cable subscription fees imposed by the Federal Internal Revenue Service.

[18] George and Yolanda Barco played important roles in obtaining the regulatory rulings that allowed cable companies to use three inches of space on utility poles in exchange for reasonable fees, an achievement of huge value to the industry.

In 1962 George Barco argued that since a CATV company simply received broadcast programming and shared it with subscribers, it was not a transmitter.

[10] George and Yolanda Barco made many donations to the University of Pittsburgh School of Law, amounting to $11 million in total.
