Apple and Google's corporate brands dropped in an annual survey while Amazon.com maintained the top spot for the third consecutive year.

Meanwhile, electric carmaker Telsa rocketed higher after sending a red Roadster into space. 

IPhone maker Apple dropped to 29th from its previous position of fifth, and Google dropped from 8th to 28th. 

Apple had ranked second as recently as 2016, according to the annual Harris Poll Reputation Quotient poll released today. 

The poll, conducted since 1999, surveyed 25,800 US adults from December 11 to January 12 on the reputations the "most visible" corporate brands. 

John Gerzema, CEO of the Harris Poll, told Reuters the likely reason Apple and Google fell was that they have not introduced as many attention-grabbing products as they did in past years.

"Google and Apple, at this moment, are sort of in valleys," Gerzema said. "We're not quite to self-driving cars yet. We're not yet seeing all the things in artificial intelligence they're going to do." 

Meanwhile, Amazon.com held on to the top spot, which it has held for five years with the exception of 2015, when it slipped to second. 

Gerzema attributed Amazon's ranking to its expanding footprint in consumers' lives into areas like groceries via its Whole Foods acquisition. 

Elon Musk's Tesla climbed from ninth to third on the strength of sending Tesla Roadster into space aboard a SpaceX rocket - despite fleeting success delivering cars on time on earth, Gerzema said. 

"He's a modern-day carnival barker - it's incredible," Gerzema said of Musk. "This 'The Right Stuff' attitude is able to capture the public's imagination when every news headline is incredibly negative. They're filling a void of optimism." 

Facebook's reputation improved in the 2018 study, despite being the target of questions from US politicians about the role of social media in Russia's efforts to influence the US presidential election in 2016. 

Facebook ranked 51st, its best showing since 2014 when it ranked 38th, the highest the firm ever ranked in the poll. 

Last place went to Japanese auto parts supplier Takata, whose air bags can explode with too much force and have been linked to at least 22 deaths and hundreds of injuries.

This prompted the largest recall in automotive history and forced Takata and its US unit, TK Holdings, into bankruptcy.
