The projector (kinetoscope) was invented in 1893
The flourescent light bulb was invented in 1827.
Thomas Edison is credited with inventing the light bulb in 1879. He improved upon previous designs and developed a long-lasting and commercially viable light bulb.
Some inventions that did not come out of Edison's laboratory at Menlo Park include the telephone (invented by Alexander Graham Bell), the airplane (invented by the Wright brothers), and the light bulb (although Edison improved upon existing designs).
The first thermometers were made by Galileo Galilei in the 1500s. However, the modern thermometer as we know it was developed in the 18th century by various scientists, including Daniel Gabriel Fahrenheit and Anders Celsius. Thermometers have since been improved upon and used widely for measuring temperature in various fields.
Shoes are constantly being invented and improved upon. Some shoes could have been invented just yesterday or last week for example.
The nebulizer was invented by a German scientist named Carl Paul Gottfried von Sömmerring in the late 18th century. It has since been improved upon by various researchers and inventors to become the device used today for delivering medication in a mist form for respiratory conditions.

yes
All the questions that have been flagged are usually the ones that need to be improved, questions that do not make sense should also be attempted to be improved upon.
The flourescent light bulb was invented in 1827.
Yes this is possible. For example: How do you think the plan can be improved upon?
It hasn't been replaced with anything, just improved upon by variants.
Lee de Forest was the inventor of the first electronic amplifying tube, the triode. His understanding of how his invention worked was far from correct, but nevertheless he had invented the first electronic valve. Rectifying tubes had been invented earlier by J A Fleming, and it was these that de Forest improved upon - magnificently.
The first iron was a heated rooling pin used in Greece around 400 B.C. The first flat irons appeared in Europe in the 1300s, The electric iron was invented in the 1880s when electricity became widely available in homes. The first electric iron was patented by Henry W. Seeley in 1882 and has been improved upon ever since.
