The Industry Standard, the magazine that charted the rise and fall of the dot.com bubble, has itself imploded.

Standard Media International will stop publication of the journal on Monday and said it will file for bankruptcy if a buyer cannot be found by then. All but 15 of 180 staff are being laid off after the magazine fell victim to a sharp slump in advertising revenues from dot.com companies.

The announcement follows the collapse of financing talks with majority owner International Data Group. One senior editor said: "We knew it was in trouble, because it has been in trouble all year but this was sudden." The Standard's launch in 1998 was one of the most commercially successful in publish ing history and the magazine went on to encapsulate the zeitgeist of the era.

Each month it would throw lavish "rooftop parties" at fashionable hotels around San Francisco where entrepreneurs, venture capitalists and investment bankers would swap business cards and gossip. Record advertising revenues from technology firms and financial institutions helped the magazine to an enviable position of financial health and allowed it to pay unusually generous salaries to a staff of 300. As dot.com fever spread across the Atlantic a European edition was launched but almost as soon as the Americans had landed they started to retreat.

A collapse in the value of many internet companies put the brakes on advertising revenues and the Standard was forced to retrench.

Standard Media, which rang up sales of $140m last year, expects revenue to be nearer $40m this year. The Industry Standard's European edition closed in April. The shutdown comes just weeks after the closure of rival magazine Business 2.0.

"This is a very sad day for everybody who has helped make the Industry Standard a great publication," said Jonathan Weber, editor in chief.
