Updated: The names were rumored in recent weeks, but Yahoo's announcement this afternoon makes it official.

Chapple, 55, was on a flight this afternoon and could not immediately be reached for comment.

Some details on Chapple, from our archives:

He was CEO of Nextel Partners in Kirkland from 1998 to June 2006 when it was sold to Sprint Nextel for about $9 billion. Craig McCaw, who was helping to reorganize Nextel Communications in 1998, asked Chapple to to run a company that would provide services in rural and midsized markets for Nextel. The sale netted Chapple more than $50 million.

Later that year, Chapple broke his vow to retire, starting Hawkeye Investments in October 2006. The private equity firm made a $1 million investment in January in Woodinville-based Loctronix, which is working on technology to help global positioning systems to work indoors and become more accurate.

Also on Chapple's resume:

-- Past president of the Vancouver Grizzlies (NBA) and Vancouver Canucks (NHL);
-- Chairman of Cellular One, a brand operated by McCaw Cellular Communications, which later became AT&T Wireless
