HOW TO START YOUR OWN SUCCESSFUL 900 NUMBER

OVER 6,500 COPIES SOLD
Bob Bentz’s Opportunity is Calling, published in 1993, is the best selling book in the history of the American 900 number industry. While 900 numbers have long been gone from the United States business scene, their legacy remains an interesting period within the telecom, marketing, and business community.
Bentz was part of the co-founders and management team at Philadelphia-based Advanced Telecom Services. The company grew from a start up to $62.2 million in annual revenue with offices in the United States, Canada, United Kingdom, Czech Republic, and Taiwan.
Its impressive 900 number client list included 65 Division-1 college sports teams, 20 NFL teams, and several MLB and NBA teams. It provided 900 numbers for the World Wrestling Federation, World Championship Wrestling (WCW), Extreme Championship Wrestling (ECW) and several superstars including Hulk Hogan and Randy “Macho Man” Savage. The company provided 900 number-based voice personals and its proprietary Crossword Puzzle Answer Line to many daily newspapers, including the Newark Star-Ledger, New York Post, New York The Daily News, and USA Today. Pay per call services were also provided to the US Catholic Church, the Michael J. Fox Foundation, and the March of Dimes.
