Senior Microsoft executive Kevin Johnson has criticised Yahoo's search deal with Google as anti-competitive and bad for advertisers, at a debate featuring representatives of leading internet companies at the Cannes International Advertising Festival.
Microsoft's Johnson cut in: "If 'win' is consolidating 90% of the paid search market [in the US] to Google then that's a win".
He said that from an industry perspective advertisers were not likely to be well served by "the search industry consolidating around a small number of platforms". Johnson added that Microsoft's Yahoo takeover bid in February offered a "significant premium" in an offer that was designed to be "fast and friendly" to move quickly in the fast-moving internet world.
I've had a great opportunity to get to know Jerry and the Yahoo board, they made a business decision and there are implications in that," he added, responding to a question from Sorrell about dissident investor Carl Icahn's move to oust the Yahoo board.
Johnson, the author of an internal letter made public earlier this week that revealed Yahoo had turned down a $9bn search advertising deal with Microsoft added that against an "entrenched competitor" like Google the company had to "innovate and disrupt".
This was the thinking behind the launch of the "cash back" offer to advertisers when consumers buy a product after using Microsoft's search service.
"The concept of search is to link buyers and sellers so why does the middleman keep all the money," he said in a thinly veiled pop at rivals. "We have to breakthrough in search, we are not where we need to be at."
