Nintendo on Wednesday said it will allow current Switch games to be played on the hit console’s successor as it looks to drum up excitement among its current user base for the highly-anticipated device.

Shares of Nintendo closed 5.8% higher in Tokyo on Wednesday, after the announcement.

“Investors think this is a sign Nintendo’s next device will not be a risky experiment but rather a continuation,” Serkan Toto, CEO of Tokyo-based games consultancy Kantan Games, told CNBC.

“I believe investors want Nintendo to adopt the iPhone approach of gradually improving a winning product instead of trying to reinvent the wheel with every new console generation.”

Backward compatibility of games is critical for console makers for several reasons: firstly, when new consoles launch, they often do not have a huge amount of games to choose from. Making older games available for the new Switch will boost the device’s appeal on this front.

Secondly, current Switch users who are thinking of purchasing new games ahead of the new console launch may hold off until after its debut. Making current games playable on the Switch’s successor removes that concern.

The Switch is Nintendo’s second-best selling console in history, behind the Nintendo DS.

But demand for the Nintendo Switch, which was first released in 2017, is slowly beginning to fade — albeit from high levels. Investors have been waiting for more details about the console’s successor, which the company said it will announce in its fiscal year ending March 2025.

Nintendo managed to breathe new life into the nearly eight-year-old console last year by releasing games involving top brands like Zelda and Pokemon, as well as expanding into areas like movies.

Google has been moderating and removing employees’ internal election-related conversations, CNBC has learned. 

Ahead of Tuesday’s U.S. elections, Google executives warned employees to keep political opinions and statements away from a popular internal discussion forum called Memegen, according to correspondence viewed by CNBC. Despite the warnings, employees continued posting memes related to the election and criticizing the company’s policies on Tuesday.

The most recent leadership guidance shows the company is taking expanded action to temper internal political discussions. Google CEO Sundar Pichai on Monday sent a memo reminding employees that people turn to the company’s services for “high-quality and reliable information.” That includes through the company’s Google Search, Google News and YouTube services.

“Whomever the voters entrust, let’s remember the role we play at work, through the products we build and as a business: to be a trusted source of information to people of every background and belief,” Pichai wrote. “We will and must maintain that.”

As one of the most important tech leaders in the U.S., Pichai himself has been pulled into the broader political discussions of late. Republican nominee Donald Trump claimed to have multiple phone calls with Pichai in recent weeks.

Google has been cracking down on internal conversations since 2019 when the company introduced a policy barring employees from making statements that “insult, demean, or humiliate” their colleagues. The rules also discouraged employees from engaging in a “raging debate over politics or the latest news story.”

That policy signaled a significant culture shift for the company. Some employees pushed back against the restrictions, saying they were too broad, and in 2020, the company said it was expanding its internal content moderation practices, requiring employees to more actively moderate internal discussions, CNBC found at the time.

Since 2021, Google has dealt with internal dissent regarding Project Nimbus, which is a $1.2 billion joint contract with Amazon to provide the Israeli government and military with cloud computing and AI services. Google briefly shut down an internal message board this March after employees posted comments about the company’s Nimbus contract.

In a 2019 settlement, the U.S. National Labor Board ordered Google to post a list of employee rights at its headquarters that included the right to discuss workplace conditions. That came after a former Google employee filed a complaint alleging that the company restricted free speech and fired him for expressing conservative views, which Google refuted.

The company declined to comment.

Perplexity AI, the artificial-intelligence search engine startup, is in the final stages of raising $500 million in funding at a $9 billion valuation, a source familiar with the situation told CNBC.

The startup competes against the likes of Google and ChatGPT-maker OpenAI. Perplexity most recent valuation was $3 billion in June. Institutional Venture Partners, a Bay Area-based firm, is leading the new round, according to the source, who requested anonymity since the funding is not yet public.

Perplexity started the year with a roughly $500 million valuation. Since then, the company has continued to attract investor interest amid the generative AI boom, raising four funding rounds so far this year.

Last week, OpenAI launched a search feature within ChatGPT, its viral chatbot, that positioned it to better compete with Perplexity, as well as leading search engines like Google and Microsoft‘s Bing. OpenAI’s search feature offers up-to-the-minute sports scores, stock quotes, news, weather and more, powered by real-time web search and partnerships with news and data providers, according to the company.

Despite the AI boom, Perplexity has been embroiled in controversy due to accusations of plagiarizing content from media outlets. The New York Times last month sent Perplexity a “cease and desist” notice, claiming that the startup scrapes the news outlet’s content to generate answers. Perplexity has denied the allegations.

In July, Perplexity debuted a revenue-sharing model for publishers. Any time a user asks a question and Perplexity generates ad revenue from citing an article in its answer, Perplexity will share a percentage of that revenue with the publisher, the company said.

Media outlets and content platforms including Fortune, Time, Entrepreneur, The Texas Tribune, Der Spiegel and WordPress were among the first to join the company’s “Publishers Program.” Dmitry Shevelenko, Perplexity’s chief business officer, told CNBC in a July interview that if three articles from one publisher were used in one answer, the partner would receive “triple the revenue share.” Perplexity worked on its revenue-sharing model since January, and the company’s goal is to have 30 publishers enrolled by the end of the year, Shevelenko said.

Perplexity’s app has been downloaded more than 2 million times, and it answers more than 230 million queries a month, the company said in August. U.S. queries have increased eightfold in the past year, according to a pitch deck for potential advertisers that was viewed by CNBC.

The Wall Street Journal was first to report on the new funding round.
