NEW YORK (AP) — It should have been a proud moment for TV: A much-hyped sports event drawing in millions of paying viewers and showcasing the clout still held by traditional media heavyweights. Instead, the broadcast of Floyd Mayweather-Manny Pacquiao fight in Las Vegas was marred by technical snafus and got sucker punched by Internet streamers, exposing the industry's vulnerabilities. An estimated 3 million households were expected to buy pay-per-view access to the fight at nearly $100 a pop Saturday night.
