* If you think NY1 has been around longer than 20 years, you’re not alone. So does NY1 anchor Pat Kiernan. “We must live in dog years,” he said. “It doesn’t feel like we’re almost approaching adulthood, it feels like we’ve been around for a long time.” Kiernan attended the 20th anniversary party on Thursday, where the network received a proclamation from Mayor Michael Bloomberg, who claimed he wrote “every letter and every word” in calligraphy. Other guests included Police Commissioner Ray Kelly, Public Advocate Bill de Blasio, Manhattan Borough President Scott Stringer, City Comptroller John Liu, Council Speaker Christine Quinn, Rep. Jerrold Nadler and Sen. Chuck Schumer, who scampered off before we could corner him and ask if he could set us up with anyone. Lest anyone think the party was frivolous, we did witness a semi-historic event – state Comptroller Tom DiNapoli and the MTA’s Joseph Lhota burying their Twitter feud. The men have been duking it out since the comptroller released an audit critical of the MTA. “We’re best friends now,” Lhota said. DiNapoli credited NY1 for smoothing relations. “We want to get the point across that we can be in the same room – the media brought us together,” he said.
