Repeat after us: Giant companies aren’t always bad. Especially when they use some of their overflowing money stash’s for the greater good. News Corporation, Viacom, The Walt Disney Company and NBC Universal are doing their part, as they’ve all pledged donations to Hurricane Sandy relief efforts.

Rupert Murdoch got things going by pledging one million from News Corporation. “Newscorp giving $1million to help families in NY and NJ badly hurt by Sandy,” Murdoch tweeted. “Hope other companies will do same.”

Viacom is donating $1 million, half to the Mayor’s Fund for NYC and half to local organizations that are helping Connecticut, Long Island, New Jersey and Westchester County get back on their feet. Disney is also splitting its $2 million donation; half will go to the Red Cross and the other million to assorted charities.

NBC Universal is taking a slightly different route, as it plans to air a fundraising special Friday night at 8 p.m. Matt Lauer will host the program, which will feature performances by Jon Bon Jovi, Christina Aguilera, Bruce Springsteen, Billy Joel and Sting.
