General Mills, Pfizer and Audi have suspended advertising on Twitter

According to foreign media reports, according to foreign media reports, people familiar with the matter said that more and more brands suspended advertising on the platform after Musk's acquisition of Twitter, including food company General Mills, Oreo maker Mondelez International, Pfizer and Audi of Volkswagen.

Kelsey Roemhildt, a spokesman for General Mills, has confirmed that the company has suspended advertising on Twitter and said it will continue to follow this new direction and evaluate marketing spending.

Some advertisers are understood to be concerned that Mr Musk may relax content censorship, which they fear will lead to an increase in undesirable content on the platform, and because of uncertainty in the company as Twitter executives leave and Mr Musk is considering a series of changes.

About 20 clients have suspended advertising spending on Twitter, according to executives at large advertising agencies. Many executives are uneasy about the sudden departure of Twitter advertising sales and marketing executives, and some ad buyers say brands may shift the advertising revenue currently allocated to Twitter to other technology platforms.

Musk has also been fighting for platform advertising and is trying to convince advertisers that Twitter is still safe. Since Mr Musk tweeted last week that "Twitter will not be a place to abuse freedom of expression", he has held several meetings with some of the world's largest advertising agencies. On Wednesday, Musk made a video call with WPP PLC, the world's largest advertising agency, and some of its clients, such as Coca-Cola, Unilever and Google, according to people familiar with the matter.
