Aug 22 (Reuters) - Nvidia ( NVDA ) and Jeff Bezos-backed

Perplexity AI said on Thursday that it plans to introduce

advertising on its artificial intelligence-powered search

platform by the fourth quarter.

Last month, the AI startup launched a program for

publishers with an initial batch of partners, including TIME,

Der Spiegel, and Fortune, in which it plans to share revenue

from interactions where a publisher's content is referenced.

Since ChatGPT first launched in November 2022, major

search engines have been trying to integrate AI into web search,

and analysts have viewed AI-assisted search as a threat to

Google's dominant position in the industry ever since the AI

boom started.

Microsoft ( MSFT ) has adopted OpenAI technology for its

Bing search engine through its early investment, while Google

rolled out AI-powered summaries for the wider public at its

developer conference in May.

In April, Perplexity AI raised $62.7 million from

existing investors such as Nvidia ( NVDA ), and new investors including

Garry Tan, CEO of Y Combinator, and Brad Gerstner, founder and

CEO of Altimeter Capital.

The fundraising round valued the company at more than $1

billion, doubling its valuation from three months earlier.
