In 1975, he produces 900 pages automatically for the phone book
of São Paulo in 72 hours of computer. In November of 1999,
the Pi Cheng accomplishes similar task for the 5.000 pages of
São Paulo's phone book in less than 30 minutes, with an
operational cost of about 1% of the cost 25 years before.
In 1991, after passing for the management of Listel's Information

The current team of DPI is composed by professionals with large
tradition and competence in the phone books and yellow page market.
This competent structure is enlarged by a net of specialist-consultants
of different areas as Sales, Marketing, Production and Distribution
for best to assist its customers' demand.
