None begrudges him his success. Last month, Cridge came top of a Campaign poll that asked the online advertising industry to name its most influential pioneer. Yet those who voted for him say that Cridge is not a pioneer in the strictest sense: someone who pushes the boundaries or breaks the mould. Rather he is a focused, amiable, down-to-earth operator who has achieved what he has by keeping things simple.
"I'm pretty sure Mark will laugh his head off when he sees his name in that list," Cridge's opposite number at the rival agency Play, Jon Sharpe, said. "He lacks conceit and arrogance to an almost unnerving level. He's built a great agency, which has done some great work, and in that sense he's been influential."
If there is one criticism that could be levelled at Cridge, it is that glue has been noticeably quieter this year. It hasn't contested its usual high quota of pitches, and its creative output is someway short of prolific.
The creative heights of "noodle web" and "hysterical girlfriend" for Pot Noodle, which both won gold Cyber Lions at Cannes last year, were created in 2003. Its Campaign New-Media Agency of the Year accolade was earned back in 2002.
But in this relatively quiet year, glue has continued to produce quirky, entertaining online advertising that the rest of the industry has tried so hard, for so long, to copy.
A charming viral for Procter & Gamble's Pringles brand, and another suggestive effort for Unilever's "slag of snacks" Pot Noodle (called "horn") have been sure signs this year that its creative juices haven't dried up. Indeed, its latest work for Virgin Money is further evidence of what the best interactive agencies can do to brighten up the drabbest of sectors on the internet.
Campaigns aside, when he hasn't been promoting online creativity via the Creative Showcase, and judging various industry awards (including Campaign Digital), Cridge has been occupied bolstering his agency. Miranda Ross, the head of planning at Harrison Troughton Wunderman, named as glue's head of planning in April, was one of the 20 new faces he's brought in this year. Glue now has 65 staff. Not bad going for an agency just six years old.
By glue's standards, a bronze Cyber Lion this summer (for Pot Noodle) might have been less than Cridge would have hoped for at Cannes. But don't forget that glue won Best Digital Agency at the IPA's Best of the Best Awards in February for its consistently strong work for T-Mobile, COI Communications, Unilever, the Royal Marines and Virgin Money. And then, of course, there are these awards, in which glue was shortlisted more than any other agency.
The agency now has more staff than FCB London, Wieden & Kennedy or Naked, and anticipates turning over £4 million by the end of 2005 - nearly 25 per cent up on 2004. If Cridge were a year younger, he'd probably be our Young Digital Achiever of the Year, too.
