In 1993, TANGER enters the market of information services and after a year’s development introduces the first Czech public database service EOTEL on-line (Economic information on-line by means of a TELephone).

The product as such was a result of the company’s own development and was known on the market under the general commercial name EOTEL on-line, specialized product parts under the names EOTEL ProSped (traffic information, forwarding), EOTEL SATinvest, which is now run under the name EOTEL NETinvest (information from capital and financial markets, including its conversion into products for technical analysis of securities - backoffice).
The service gradually underwent fundamental technical changes regarding namely the access to the service - from modem connection through distribution of data by analog and then digital transmission via a satellite to the Internet.
