HBO, Showtime Sue to Block Pacquiao-Mayweather Fight Webcasts

Home Box Office Inc. and Showtime Networks Inc. asked a judge to knock out the unauthorized live streaming of the May 2 fight between Floyd Mayweather Jr. and Manny Pacquiao, the most lucrative boxing match in history.

Revenue from the Las Vegas bout, generated largely from pay-per-view purchases and ticket sales, could exceed $300 million, according to Pacquiao’s promoter, Bob Arum.
