Commercials and informercials followed, anchored by the high-energy Mays showing how it's done while tossing out kitschy phrases like, "Long live your laundry!"
Recently he's been seen on commercials for a wide variety of products and is featured on the reality TV show "Pitchmen" on the Discovery Channel, which follows Mays and Anthony Sullivan in their marketing jobs. He's also been seen in ESPN ads.
His ubiquitousness and thumbs-up, in-your-face pitches won Mays plenty of fans. People line up at his personal appearances for autographed color glossies, and strangers stop him in airports to chat about the products.
"I enjoy what I do," Mays told The Associated Press in a 2002 interview. "I think it shows."
Mays liked to tell the story of giving bottles of OxiClean to the 300 guests at his wedding, and doing his ad spiel ("powered by the air we breathe!") on the dance floor at the reception. Visitors to his house typically got bottles of cleaner and housekeeping tips.
Discovery Channel spokeswoman Elizabeth Hillman released a statement Sunday extending sympathy to the Mays family.
"Everyone that knows him was aware of his larger-than-life personality, generosity and warmth," Hillman's statement said. "Billy was a pioneer in his field and helped many people fulfill their dreams. He will be greatly missed as a loyal and compassionate friend."Please view/sign the guest book
