FYI
There have been about 4000 launches (some with multiple payloads) and my guess is that several hundred of the satellites involved are still active. Nine individual countries have launched satellites (USA, Russia, Japan, China, France, India, Israel, Australia, UK) as well as international consortia (ESA, the European Space Agency, being the most important of those). A large number of countries have enough money and could easily acquire the technology to launch satellites, but choose for economy and convenience to either have another country launch their payloads or to participate in the space projects of other nations.
