This week on The Stack: Latest Ad Tech Acquisitions; Google and Apple in Antitrust Spotlight; Today's MadTech Daily  

This week saw the news of two big ad tech acquisitions. The Trade Desk announced it would be acquiring Sincera, with the deal expected to close later this quarter. Meanwhile, T-Mobile is acquiring OOH specialist Vista Media. 

Google found itself in the antitrust spotlight again – no surprise there. The UK’s Competition and Markets Authority officially launched its investigation into Google’s Search services, aiming to determine whether the company has strategic market status in search advertising activities, and whether these services are delivering good outcomes for people and businesses in the UK. Apple’s UK antitrust trial also kicked off, with the tech giant facing allegations that it has violated competition law.  

Looking at the latest in the APAC region, TikTok rolled out message ads, while it continued its battle against the US’ ban-or-divest bill.
