How did the story of Frindle become a national concern?

The frindle story would have died out naturally on its own if not for a television reporter who read about Nick in The Westfield Gazette and decides to send the story to the network in New York. They interview a rather disapproving Mrs Granger then go to talk with Nick and his mother who are careful not to say anything controversial. The following day the report airs on the CBS evening news. Nick is wanted for interviews with all of the most popular television shows and in all the most popular magazines and the word frindle spreads nationwide. Bud Lawrence's attorney realizes that the whole country now knows that Nick made up the woes and suggests that in order to avoid a lawsuit he offers Nick a cut of his profits. He signs a deal with Nick's dad that gives Nick royalties on every sale. Sales are strong and Westfield even adds "Home of the original frindle" to the sign on Route 302.
