Brave Bison → System1
Brave Bison has reported that, as of its latest update, it has received zero acceptances for its proposed takeover of System1. The status of the acquisition remains unchanged, with no shareholders agreeing to the offer so far.
Brave Bison Group PLC and System1 Group PLC have released an update regarding the current acceptance levels for their proposed acquisition deal. The announcement provides stakeholders with the latest information on the progress of the transaction.
Brave Bison is advancing its plans to acquire System1 Group at £3.60 per share, having secured additional support for the takeover. The deal would bring System1 Group under Brave Bison’s ownership, pending final approvals.
Nielsen → DoubleVerify $2.15B (enterprise value; $13.60 per share in cash)
Nielsen agreed to buy the largest independent ad verifier, one of the vendors advertisers can use to pre-screen Google search partner sites. The deal awaits shareholder approval and closing.
Outbrain → Teads (from Altice) $1B (approximate value at announcement; closed on revised terms of $625M cash plus 43.75M shares)
Outbrain bought a video ad company and took its name, moving one of the two main native-to-search traffic sources towards brand advertising. The group now trades as Teads (TEAD).
Perion Network → Hivestack $100M (cash at closing, plus up to $25M in retention payments)
Bought with profits from the Bing search business months before that business shrank. Hivestack's technology later became the base of the Perion One platform that replaced search as the company's focus.
CentralNic (now Team Internet Group) → Codewise (Zeropark and Voluum) $36M
Added a traffic network and the best-known affiliate tracker to a group that already owned a feed platform and a parking company, putting several links of the arbitrage chain under one owner.
CentralNic (now Team Internet Group) → Team Internet AG (ParkingCrew and Tonic) $48M ($45M of it in cash)
A domain registry company bought a parking platform and an arbitrage feed platform. The monetisation business soon outgrew the domain business, and the group later took the Team Internet name.
Miteno Communication Technology consortium → Media.net $900M (all-cash, paid in stages)
A Chinese consortium paid $900 million for a contextual ad network built on Yahoo and Bing search demand. It showed how much a business that puts search ads on content pages could be worth.
A young arbitrage company bought a dot-com era metasearch business with Dogpile, WebCrawler and long-standing search-engine agreements. Those sites and relationships became the base of System1.
Perion's first big step away from search. Diversifying into display advertising is what kept the company standing when its Bing search revenue collapsed in 2024.
The largest registrar bought a leading domain sales platform, tying the aftermarket and parked-domain monetisation to the place where most domains are registered.
IAC bought the fourth-largest US search engine. After Ask stopped building its own search technology in 2010, the business became one of the largest search-to-search arbitrage operations, buying search traffic and reselling it through partner ads.
Marchex → Name Development (domain portfolio) $164M ($155.15M cash plus $9M in stock)
The biggest early bet on type-in traffic: a listed company paid about $164 million for a portfolio of domain names monetised with pay-per-click ads. It showed how valuable parked domains looked at the height of the model.
Yahoo → Overture Services (formerly GoTo.com) $1.63B (cash and stock)
Yahoo bought the inventor of pay-per-click search ads and of the syndicated search feed, which had been its own supplier. The deal made Yahoo a feed provider and set up two decades of Yahoo syndication.
Google bought the company whose AdSense product matched ads to the meaning of a page, and took over the name. Its domain-ads technology grew into AdSense for Domains, which funded the parking industry until 2026.
