 In the 1990s, Tele-Communications Inc. (TCI) and Time Warner scrapped efforts to create internal billing software and hired CSG International. The 15-year agreement CSG signed with TCI on August 11, 1997 made CSG the largest vendor in the industry and was the primary contributor to its growth in the '90s. By 2001, the deal was responsible for 45 percent of CSG's revenue. As part of the deal, CSG also acquired TCI's internally developed software, SummiTrack, for $ 106 million. CSG's services to TCI included billing, customer management and payment processing for TCI customers. In October 1997, CSG International signed its first deal with a utilities company, mc2.
