In the early 1970s, the access to IPSA's computer facilities were extended into Europe via trans-Atlantic cable. The I.P. Sharp network offered the company's communications capability, its on-line SHARP APL software and application program environment as well as private and public databases and libraries. In mid 1970s, IPSA introduced its own internally developed packet-switching network in Europe, and later world-wide.

By the early 1980s, IPSA was best known for its reliable, high-performance public time-sharing service available through an efficient world-wide communications network--IPSANET--one of the largest and most advanced in the world. By the end of the 1980s, IPSANET was linking over 800 cities in 80 countries and territories. It had wholly-owned subsidiaries in Australia, Austria, Belgium, Denmark, France, Hong Kong, Ireland, Italy, The Netherlands, Norway, Singapore, Spain, Sweden, Switzerland, UK, USA, and West Germany. The company maintained one of the world's largest collections of on-line business-oriented data. Access to IPSANET was via a phone line which was a local call to a mainframe computer located at IPSA's computer center in Toronto. The network was successfully used by many international companies world-wide. Its success was due to its extent and reliability, its contents and services.

Since mid 1980s, data could also be retrieved from the I.P. Sharp Online Service using a personal computer and downloaded efficiently for local analysis and processing by user programs or popular software such as LOTUS 1-2-3, VisiCalc, or Compu Trac.

In 1987, I.P. Sharp was acquired by Reuters Holdings PLC. In 1993, a newly established software company Soliton Associates Ltd. of Toronto completed the acquisition of assets related to the APL software business from Reuters Information Services (Canada) Ltd, including SHARP APL software.
