TikTok has been dealt a devastating blow as a US bill has been signed into law forcing owner ByteDance to sell within a year or face its removal from app stores. 

The stakes are higher than in 2020—China's opposition to a divestment will make an optimal sale harder to conclude, so all sides must be prepared for a ban.   

The TikTok bill introduces extraordinary new powers in the context of the US and China's broad systemic rivalry, though online consumer benefits will be limited.  

Sony PlayStation’s next CEO will have hard decisions to make: compete against a resurgent multiplatform Microsoft, or retreat and defend an increasingly rickety PlayStation console model.

New gaming hardware will have an outsize influence in the year ahead, giving gamers unprecedented choice, starting with XR headsets and continuing to a likely new Nintendo Switch.

YouTube’s foray into browser-based games will be the service to watch in 2024. If successful, streaming services, including Netflix, will be on track to become heavyweight game platforms.

Microsoft dominated PCs and Nokia mobile phones, but both are irrelevant in the dominant model for tech in the next decade, smartphones and tablets. An acquisition may have been necessary, but by itself it solves nothing.

Smartphones are now half of all mobile phone sales, and the 255m smartphones and tablets sold in Q2 2013 dwarf the 76m PCs sold. Microsoft now powers less than a quarter of all the personal computing devices being sold.

Microsoft retains a leading position in enterprise and in console gaming. But if it cannot return to relevance in consumer, the strength of the whole business will suffer.
