CompuServe was an American online service, the first major commercial one in the world. It opened in 1969 as a timesharing and remote access service marketed to corporations. After a successful 1979 venture selling otherwise under-utilized after-hours time to Radio Shack customers, the system was opened to the public, roughly the same time as The Source. H&R Block bought the company in 1980 and began to more aggressively advertise the service.
