Google is looking to place advertisements on refrigerators, thermostats, dashboards and other ads-free objects, according to a letter penned by the tech giant to the Securities and Exchange Commission (SEC).
The letter was sent to the SEC in December and published by the government organization on Tuesday, according to CNET.
Google said in the letter that the definition of the word "mobile" is always changing.
The search giant added that advertisements could be served on different devices besides smartphones, desktops and tablets, Marketing Land reported.
"We expect the definition of 'mobile' to continue to evolve as more and more 'smart' devices gain traction in the market. For example, a few years from now, we and other companies could be serving ads and other content on refrigerators, car dashboards, thermostats, glasses and watches, to name just a few possibilities," the company wrote in the letter.
Google is looking to offer a new feature called "Enhanced Campaigns" for advertisers to use. These ads could be targeted toward the right people at the right time by being served through a variety of devices and experiences, such as thermostats, smartphones and cars, The Economic Times reported.
"Enhanced Campaigns allows our advertisers to write one ad campaign, which we serve dynamically to the right user at the right time on whatever device makes the most sense," the company wrote. "Because users will increasingly view ads and make purchase decisions on and across multiple devices, our view of revenue is similarly device-agnostic."
The company said Google Glass will not feature ads, Marketing Land reported. The company has, however, acquired a patent for a technology called "pay-per-gaze".
After Google's purchase of Nest Labs, the home automation company said "Our privacy policy clearly limits the use of customer information to providing and improving Nest's products and services."
Tony Fadell, founder of Nest, said the new ads would not appear in the company's thermostat, and that the company is not looking to have an ads-based model, The Economic Times reported.
"We've contacted the SEC to clarify our 2013 filing, it does not reflect Google's product roadmap," Fadell said.
