There is a definite difference. A range of, means all things occurring in between 2 points. So the range of ages in the group was 14 years old to 60 years old. A series is defined as something that happens consecutively. Example, we had a series of crimes lately , means one crime after the next. Or a movie series, means one type of movie in a series, one following the next.

Range = the variety/ mixture/choice/selection. Series = occurring in order one after the other. The TV series and range example is confusing. It wrongly indicates they are interchangeable they are not. The context will be different. Just like SU.KI says. A TV series is a programme that continues its storyline day after day or week after week. A range of TV programmes is the menu/choice of programs each channel offers every day. TV program = American TV programme = more British but program is now also being used by some people. British English tends to reserve the word "program" for a computer program or a set of instructions programmed into a machine/device. Programme in British English is used to describe a series of events/shows/films/plays etc

There IS a definite difference. 'Range' indicates the variety. For example, 'a range of people' might suggest men and women of all different ages, backgrounds and abilities; 'a range of colours' means that an item is available in a number of different colours; 'a range of products' a wide choice of products of various prices and specifications. The word is often used to show an extent, say, from the smallest to the biggest e.g. a range of ages from 16 to 73, a range of prices from £30 to £100. 'Series' indicates chronological sequence. A TV series is composed of a number of episodes, shown in sequence, from the first to the last. If a sports team suffers a series of defeats, for example, this means that they lost several games, one after another. A series of events refers to a number of events which occured, one after the other. In answer to your question "How about 'a range of products' and 'a series of products'?": 'A range' refers to the variety of products which are on offer at any one time. 'A series' would suggest that they launched one product after another, perhaps improving and modifying as they went along, and perhaps even withdrawing the earlier products as they bring out the subsequent one. These words are not interchangeable.

Hiya They can be interchangeable depending on the context. ie. A series of events OR a range of events But you would have a TV series, or a range of TV programmes
