PiperJaffray analyst Gene Munster notes that this data illustrates the mass appeal Apple's handset still carries with the marketplace.
On the day of and day after their respective debuts, the iPhone 5 garnered 2.4 million tweets; whereas, the Samsung Galaxy S 4 only managed 440,000. Notably, this is an improvement for the company but it is still far from that of the iPhone.
"We believe this demonstrates that while interest in the Galaxy S 4 is growing, Apple continues to hold a meaningful lead as the smartphone with the broadest consumer appeal," Munster said.
Interestingly, 81% of tweets about the Galaxy S4 were positive compared to just 73% for the iPhone 5. This is thought to be due to leaks which left consumers unsurprised on launch day.
