During the Olympic opening ceremonies, NBC apparently stands for Nothing But Commercials.

Viewers took to Twitter to slam the network’s frequent commercial breaks Friday night.

If frequency of televised commercials were an Olympic sport, @nbc could claim the top podium already.

Thanks NBC for showing the Olympic Opening Ceremony in the short breaks between commercials. #nbcfail pic.twitter.com/8U9suwRozb

Dear #NBC: I wouldn't need idiot commentators to explain narrative of #openingceremony if you actually showed it rather than commercials

Matt Drudge even weighed in, tweeting, “5 commercial breaks in first 30 minutes??!! Send some mosquitoes into the NBC booth!” deftly referring to the Zika outbreak in Brazil.

Others were equally as irritated:

In the US, NBC managed to splice every two minutes of the ceremony with five minutes of commercials

Okay @NBCOlympics @nbc your commercials are getting beyond annoying. What's the best channel to watch the #OpeningCeremony on?

@NBCOlympics @nbc @NBCSports I hope you're donating the revenue from commercials to rebuild Rio. Ridiculous.

Mediaite notes the first 40 minutes of the Opening Ceremonies included 14 minutes of commercials during six different breaks.
