CBS is also pursuing videotex service. Some 100 homes in Ridgewood, NJ are already receiving videotex information as part of a joint test project of CBS and AT&T. A second test will be launched by CBS early in 1983. The services provided include news, weather, sports, advertising, and shopping. Banking services may also be included in the second test. More than 60 advertisers have been signed. The purpose of the tests is to measure consumer interests and to evaluate the potential sources of revenue: subscription fees, advertising, and transaction fees.
