Residents of European travel hotspots are rallying against the effects of over-tourism for the second consecutive summer, Axios' April Rubin reports.

• Americans' summer travel to Europe is projected to increase for the fourth year in a row, per a report from travel insurance company Allianz Partners.

💦 State of play: Locals have taken to spraying tourists with water guns as a form of protest in Lisbon, Barcelona, Venice and other popular European destinations.

• Staff at the Louvre spontaneously went on strike this past Monday to protest unmanageable crowds and chronic understaffing. The work stoppage — which happened without a vote by union membership — shuttered the world's most visited museum for hours.

🏘️ Between the lines: Locals blame Airbnb for contributing to the problem, reducing housing supply and increasing prices in residential neighborhoods.

• The Spanish government last month called for the removal of nearly 66,000 short-term rental listings on Airbnb.
• Airbnb has placed the blame on hotels, saying they account for 80% of the nights tourists spend in Europe.

It's been 50 years since "Jaws" turned Hollywood on its head.

• "Jaws" became the definitional summer blockbuster — essentially creating the genre that has now fully consumed many major studios.

🍿 What we're watching: Director Steven Spielberg participated in a new documentary, "Jaws @ 50: The Definitive Inside Story," which premieres July 10 on National Geographic.

• The director had to imply the shark's existence as a workaround — which, combined with John Williams' score — built the suspense that made "Jaws" the classic it is.
